74a18ee8a5 crc32: Correct endianness of crc32 result
When crc32 is handled by the hash library, it requires the data to be in
big-endian format, since it reads it byte-wise. Thus at present the 'crc32'
command reports incorrect data. For example, previously we might see:

Peach # crc32 40000000 100
CRC32 for 40000000 ... 400000ff ==> 0d968558

but instead with the hash library we see:

Peach # crc32 40000000 100
CRC32 for 40000000 ... 400000ff ==> 5885960d

Correct this.

669dfc2ed8 fdt: Ensure that libfdt_env.h comes from U-Boot
When building host utilities, we include libfdt.h from the host, not from
U-Boot. This in turn brings in libfdt_env.h from the host, which can mess
up the types and cause a build failure, depending on the host environment.
To fix this, force inclusion of U-Boot's libfdt_env.h so that the types
are correct.

Another way to fix this is to use -nostdinc and -idirafter to ensure that
system includes are included after U-Boot ones. Unfortunately this means
that U-Boot's errno.h gets included instead of the system one. This in
turn requires a hack to errno.h to redirect things, so all in all the
solution in this patch is probably cleaner.

22a4a6c5c2 printenv: Correct out-of-memory condition check.
In common/cmd_nvedit.c, en env_print(), the wrong type is used for len.
hexport_r() returns -1 on error (like OOM), which is converted to
0xffffffff when put in an unsigned. Said value is obviously bigger then
0, and as a result an uninitialized string is then displayed. Other
usages of hexport_r() in the code correctly uses ssize_t to keep its
return value.

7525c2dac7 x86: Allow setup code to manage its own global data
Currently x86 has its own means of managing the global data and board data
(bd_t), and this code resides in start.S. With generic board, we need to
ensure that we leave this alone - i.e. don't clear it as we do on other
archs.

This fixes a problem where the memory init data is cleared which causes
the video driver to operate very slowly.

8b42dfc3b6 x86: Fix DRAM bank size init with generic board
The intention of the memory init code is that it should work the same with
CONFIG_SYS_GENERIC_BOARD and without. This is tricky because dram_init()
is called prior to relocation with generic board (matching other archs)
and after relocation without generic board.

Adjust the init sequence so that dram_init() is not called in the generic
board case, which seems like the easiest fix for now. Also ensure that
relocation addresses are still calculated.

3ebbbfe4c7 Tegra: Restore cp15 VBAR _start vector write for ARMv7
A start vector fix was added by AneeshV for OMAP4 (commit 0d479b53),
and caused the old monilithic Tegra builds to hang due to an undefined
instruction trap. Previously, the code needed to run on both the
AVP (ARM7TDI) and A9, and the AVP doesn't have a CP15 register.
I corrected this in commit 6d6c0bae w/#ifndef CONFIG_TEGRA, but
now that we use SPL, and boot the AVP w/o any ARMv7 code, I can
revert my change, and make Aneesh's change apply to Tegra.

eb222d1d7d ARM: tegra: support T33 SKU of Tegra30
Make U-Boot aware of the T33 SKU of Tegra30, and treat it identically
to any other Tegra30.

An alternative would be to simply remove the SKU checking from
tegra_get_chip_type(); most use of the value most likely simply wants
to know the current chip, not the specific SKU. Or, the function could
be split into separate tegra_get_chip() and tegra_get_sku() for the
cases where differentiation really is required.

I wonder whether tegra_get_chip_type() should printf() whenever any
unkown chip/SKU is found, although perhaps the function is called so
early that the printf() wouldn't actually make it to the UART anyway.

The KVM and Xen hypervisors for the Cortex-A15 virtualization
implementation need to be entered in HYP mode. Should the primary
board firmware already enter HYP mode (Calxeda firmware does that),
we should not deliberately drop back to SVC mode.

Actually the glitch is happening due to always toggling between slave mode

Since the spi driver only supports master mode, set the mode for all channels
always to master mode in order to have a stable, "glitch-free" SPI clock line.

8732b0700d tpm: Add TPM command library
TPM command library implements a subset of TPM commands defined in TCG
Main Specification 1.2 that are useful for implementing secure boot.
More TPM commands could be added out of necessity.

You may exercise these commands through the 'tpm' command.  However, the
raw TPM commands are too primitive for writing secure boot in command
interpreter scripts; so the 'tpm' command also provides helper functions
to make scripting easier.

For example, to define a counter in TPM non-volatile storage and
initialize it to zero:

$ tpm init
$ tpm startup TPM_ST_CLEAR
$ tpm nv_define d 0x1001 0x1
$ tpm nv_write d 0x1001 0

And then increment the counter by one:

$ tpm nv_read d 0x1001 i
$ setexpr.l i $i + 1
$ tpm nv_write d 0x1001 $i

NOR flash, but we have a direct connection between the kirkwood and the

For i.MX25/35/51, the FCB is ignored by the boot ROM, so this image is just

120ae6091d Makefile: Move SHELL setup to config.mk
make never uses the SHELL variable from the environment. Instead, it
uses /bin/sh, or the value assigned to the SHELL variable by the Makefile. This
makes the export of the SHELL variable useless for sub-makes (but still useful
for the environment of recipes). However, we want all makes to use the same
shell.

This patch fixes this issue by moving the SHELL variable setup and export to the
top config.mk, so that all Makefile-s including it use the same shell.

Since BASH is used by default, this makes it possible to use things
like 'echo -e ...' in sub-makes, which would otherwise fail e.g. with /bin/sh
symlinked to /bin/dash on Ubuntu.

2979b26323 autoconfig.mk: Make it possible to define configs from other configs
Give more flexibility to define configs that can be interpreted by make, e.g. to
define fallback values of configs like in the example below.

Before this change, the config lines:
 #define CONFIG_SPL_MAX_SIZE	2048
 #define CONFIG_SPL_PAD_TO	CONFIG_SPL_MAX_SIZE
would have been changed in autoconfig.mk into:
 CONFIG_SPL_MAX_SIZE=2048
 CONFIG_SPL_PAD_TO="CONFIG_SPL_MAX_SIZE"

Hence, a make recipe using as an argument to $(OBJCOPY):
 --pad-to=$(CONFIG_SPL_PAD_TO)
would have issued:
 --pad-to="CONFIG_SPL_MAX_SIZE"
which means nothing for $(OBJCOPY) and makes it fail.

Thanks to this change, the config lines above are changed in autoconfig.mk into:
 CONFIG_SPL_MAX_SIZE=2048
 CONFIG_SPL_PAD_TO=$(CONFIG_SPL_MAX_SIZE)

Hence, the make recipe above now issues:
 --pad-to=2048
as expected from the defined config.

a430e91643 mtd: nand: mxc_nand: Fix is_16bit_nand()
Currently is_16bit_nand() is a per SoC function and it decides the bus nand
width by reading some boot related registers.

This method works when NAND is the boot medium, but does not work if another
boot medium is used. For example: booting from a SD card and then using NAND
to store the environment variables, would lead to the following error:

NAND bus width 16 instead 8 bit
No NAND device found!!!
0 MiB

Use CONFIG_SYS_NAND_BUSWIDTH_16BIT symbol to decide the bus width.

If it is defined in the board file, then consider 16-bit NAND bus-width,
otherwise assume 8-bit NAND is used.

This also aligns with Documentation/devicetree/bindings/mtd/nand.txt, which
states:

nand-bus-width : 8 or 16 bus width if not present 8

fac150e83f powerpc/lib: fix unsafe register handling in wait_ticks
If watchdog is enabled, the arch/powerpc/lib/ticks.S::wait_ticks() function
calls the function specified by the WATCHDOG_RESET macro.
The wait_ticks function depends on the registers r0, r6 and r7 being
preserved however that is not guaranteed, e.g. if the reset function is a
C function this will probably overwrite r0 and cause an endless loop.

The following patch changes to using r14+r15 instead of r6+r7 (to resemble
what would have been generated by a C compiler) and saves all necessary
registers on the stack.

The patch has been tested on a custom MPC5125 based machine using the 512x
powerpc architecture.

c39d6a0ea5 nand: Extend nand_(read|write)_skip_bad with *actual and limit parameters
We make these two functions take a size_t pointer to how much space
was used on NAND to read or write the buffer (when reads/writes happen)
so that bad blocks can be accounted for.  We also make them take an
loff_t limit on how much data can be read or written.  This means that
we can now catch the case of when writing to a partition would exceed
the partition size due to bad blocks.  To do this we also need to make
check_skip_len count not just complete blocks used but partial ones as
well.  All callers of nand_(read|write)_skip_bad are adjusted to call
these with the most sensible limits available.

The changes were started by Pantelis and finished by Tom.

ea2453d56b dfu: Support larger than memory transfers.
Previously we didn't support upload/download larger than available
memory.  This is pretty bad when you have to update your root filesystem
for example.

This patch removes that limitation (and the crashes when you transfered
any file larger than 4MB) by making raw image writes be done in chunks
and making file maximum size be configurable.

The sequence number is a 16 bit counter; make sure we handle rollover
correctly. This fixes the wrong transfers for large (> 256MB) images.

Also utilize a variable to handle initialization, so that we don't rely
on just the counter sent by the host.

c3d2c24f6c OMAP3/4/5/AM33xx: Correct logic for checking FAT or RAW MMC
In the case of booting from certain peripherals, such as UART, we must
not see what the device descriptor says for RAW or FAT mode because in
addition to being nonsensical, it leads to a hang.  This is why we have
a test currently for the boot mode being within range.  The problem
however is that on some platforms we get MMC2_2 as the boot mode and not
the defined value for MMC2, and in others we get the value for MMC2_2.
This is required to fix eMMC booting on omap5_uevm.

Tested on am335x_evm (UART, NAND, SD), omap3_beagle (NAND, SD on
classic, SD only on xM rev C5) and omap5_uevm (SD, eMMC).

78fd004107 omap5: Allow use of a plain text env file
For production systems it is better to use script images since
they are protected by checksums and carry valuable information
like name and timestamp. Also, you can't validate the content
passed to env import.

But for development, it is easier to use the env import command and
plain text files instead of script-images.

Since both OMAP5evm/uevm boards are used primarily for development,
we allow U-Boot to load env var from a text file in case that an
boot.scr script-image is not present.

The variable uenvcmd (if existent) will be executed (using run) after
uEnv.txt was loaded. If uenvcmd doesn't exist the default boot sequence
will be started.

that OMAP maps the NOR flash to address 0x08000000 by default and so
use this as the default address for the NOR flash.

Also remove legacy code that attempts to calculate where in flash the

4de602f2b0 musb: am335x: disable bulk split-combine feature
On TI AM335x devices, MUSB has bulk split/combine feature enabled
in the ConfigData register, but the current MUSB driver does not
support it yet. Therefore, disable the feature for now, until the
driver adds the support.

One usecase which is broken because of this feature is that Ether
gadget stops working in Fullspeed mode (by un-defining
CONFIG_USB_GADGET_DUALSPEED)

After desabled this feature, MUSB driver send packets in proper size
(no more than 64 bytes) in Fullspeed mode.

This has been validated with Ether gadget in Fullspeed mode on AM335x
EVM.

d36b39bf0d spi: mxc_spi: Fix ECSPI reset handling
Reviewing the ECSPI reset handling shows two issues:

1. For the enable/reset bit (MXC_CSPICTRL_EN) in the control reg
   (ECSPIx_CONGREG) the i.MX6 technical reference manual states:

   -- cut --
   ECSPIx_CONREG[0]: EN: Writing zero to this bit disables the block
   and resets the internal logic with the exception of the ECSPI_CONREG.
   -- cut --

   Note the exception mentioned: The CONREG itself isn't reset.

   Fix this by manually writing the reset value 0 to the whole register.
   This sets the EN bit to zero, too (i.e. includes the old
   ~MXC_CSPICTRL_EN).

2. We want to reset the whole SPI block here. So it makes no sense
   to first read the old value of the CONREG and write it back, later.
   This will give us the old (historic/random) value of the CONREG back.
   And doesn't reset the CONREG.

   To get a clean CONREG after the reset of the block, too, don't use
   the old (historic/random) value of the CONREG while doing the reset.
   And read the clean CONREG after the reset.

This was found while working on a SPI boot device where the i.MX6 boot
ROM has already initialized the SPI block. The initialization by the
boot ROM might be different to what the U-Boot driver wants to configure.
I.e. we need a clean reset of SPI block, including the CONREG.

board/freescale/mx6qsabrelite/README explain a procedure to
update the SPI-NOR on the SabreLite board without Freescale
manufacturing tool but following this procedure leads to both
"sf erase" and "sf write" failing on a mx6qsabrelite board:

MX6QSABRELITE U-Boot > sf probe 1
MX6QSABRELITE U-Boot > sf erase 0 0x40000
SPI flash erase failed
MX6QSABRELITE U-Boot > sf write 0x10800000 0 0x40000
SPI flash write failed

This is because the chip-select 1 is wrong and the correct
value is 0x7300.

Since commit c1173bd0 ("sf command: allow default bus and chip selects")
the chip-select and bus arguments for the sf probe command are optional
so let's just remove it and use "sf probe" instead.

When booting a Freescale kernel 3.0.35 on a Wandboard solo, the get_board_rev()
returns 0x62xxx, which is not a value understood by the VPU

fail.

The expected values for get_board_rev are:
0x63xxx: For mx6quad/dual
0x61xxx: For mx6dual-lite/solo

So adjust get_board_rev() accordingly and make it as weak function, so that we

Maximum bus width supported by some i.MX6 boards is not 8bit like

they agree to communicate on 8bit interface while some boards support only 4bit interface.
Due to this reason the mmc 8bit default mode fails on these boards. To rectify this,
define maximum bus width supported by these boards (4bit). If max_bus_width is not
defined, it is 0 by default and 8bit width support will be enabled in host
capabilities otherwise host capabilities are modified accordingly.

It is tested with a MMCplus card.

This patch corrects the addresses used when working with Spansion/AMD FLASH chips.
Addressing for 8 and 16 bits is almost identical except in the 16-bit case the
LSB of the address is always 0.  The confusion arose because the addresses
in the datasheet for 16-bit mode are word addresses but this code assumed it was
byte addresses.

I have only been able to test this on our Octeon boards which use either an 8-bit
or 16-bit bus.  I have not tested the case where there's an 8-bit part on a 16-bit
bus.

This patch also adds some delays as suggested by Spansion.

If a part can be both 8 and 16-bits, it forces it to work in 8-bit mode if an
8-bit bus is detected.

Apart from the pulled changes, fixed few minor code cleanups and tested
on 256M29EW, 512M29EW flashes.

92809eeed2 Exynos: Tidy up the pwm_config function in the exynos pwm driver
Some small fixes in the exynos pwm driver:

1. NS_IN_HZ is non-sensical since these are not compatible units. This
constant actually describes the number of nanoseconds in a second. Renamed it
to NS_IN_SEC. Also dropped the unnecessary parenthesis.
2. The variable "period" is not used to hold a period, it's used to hold a
frequency. Renamed it to "frequency".
3. tcmp is an unsigned value, so (tcmp < 0) will never be true and the if
which checks that condition will never execute. Also, there should be no
problem if the pwm never switches, so there's no reason to subtract one from
tcmp and therefore no reason to compare it against zero. Removed both ifs. If
they weren't removed, tcmp should be a signed value.
4. Add a check for a 0 period.

c059f274ad Exynos: pwm: Fix two bugs in the exynos pwm configuration code
First, the "div" value was being used incorrectly to compute the frequency of
the PWM timer. The value passed in is a constant which reflects the value
that would be found in a configuration register, 0 to 4. That should
correspond to a scaling factor of 1, 2, 4, 8, or 16, 1 << div, but div + 1 was
being used instead.

Second, the reset value of the timers were being calculated to give an overall
frequency, thrown out, and set to a maximum value. This was done so that PWM 4
could be used as the system clock by counting down from a high value, but it
was applied indiscriminantly. It should at most be applied only to PWM 4.

This change also takes the opportunity to tidy up the pwm_init function.

The "bootmenu" command uses U-Boot menu interfaces and provides

When running this command the menu will be assembled as defined
by a set of environment variables which contain a title and
command key-value pairs. The "Up" and "Down" keys are used for
navigation through the items. Current active menu item is
highlighted and can be selected using the "Enter" key.

The command interprets and generates various ANSI escape
sequencies, so for proper menu rendering and item selection
the used terminal should support them.

cfb_console" breaks splash screen alignment which is passed in as magic
(BMP_ALIGN_CENTER) x/y coordinates. Moving the check after the alignment block
fixes this.

9a4fbe4fbd mmc: add bcm2835 driver
This adds a simple driver for the BCM2835's SD controller.

Workarounds are implemented for:
* Register writes can't be too close to each-other in time, or they will
  be lost.
* Register accesses must all be 32-bit, so implement custom accessors.

This code was extracted from:
git://github.com/gonzoua/u-boot-pi.git master
which was created by Oleksandr Tymoshenko.

Portions of the code there were obviously based on the Linux kernel at:
git://github.com/raspberrypi/linux.git rpi-3.6.y
commit f5b930b "Main bcm2708 linux port" signed-off-by Dom Cobley.

swarren changed the following for upstream:
* Removed hack udelay()s in bcm2835_sdhci_raw_writel(); setting
  SDHCI_QUIRK_WAIT_SEND_CMD appears to solve the issues.
* Remove register logging from read*/write* functions.
* Sort out confusion with min/max_freq values passed to add_sdhci().
* Use more descriptive variable names and calculations in IO accessors.
* Simplified and commented twoticks_delay calculation.
* checkpatch fixes.

6be3c9fca2 video: add a driver for the bcm2835
The firmware running on the bcm2835 SoC's VideoCore CPU manages the
display controller. Add a simple "LCD" driver that communicates with the
firmware using the property mailbox protocol. This configures the
display and frame-buffer to match whatever physical resolution the
firmware chosen when booting, which is typically the native resolution
of the attached display device, presumably unless otherwise specified
in config.txt on the boot media.

Enable this driver in the Raspberry Pi board configuration.

6d3307195d lcd: calculate line_length after lcd_ctrl_init()
When an LCD driver is actually driving a regular external display, e.g.
an HDMI monitor, the display resolution might not be known until the
display controller has initialized, i.e. during lcd_ctrl_init(). However,
lcd.c calculates lcd_line_length before calling this function, thus
relying on a hard-coded resolution in struct panel_info.

Instead, defer this calculation until after lcd_ctrl_init() has had the
chance to dynamically determine the resolution. This needs to happen
before lcd_clear(), since the value is used there.

grep indicates that no code outside lcd.c uses this lcd_line_length; in
particular, no lcd_ctrl_init() implementations read it.

The firmware running on the bcm2835 SoC's VideoCore CPU determines how
much of the system RAM is available for use by the ARM CPU. Previously,
U-Boot assumed that only 128MB was available, since this was the
smallest value configured by any public firmware. However, we can now
query the actual value at run-time from the firmware using the mbox
property protocol.

88077280c4 ARM: bcm2835: add mailbox driver
The BCM2835 SoC contains (at least) two CPUs; the VideoCore (a/k/a "GPU")
and the ARM CPU. The ARM CPU is often thought of as the main CPU.
However, the VideoCore actually controls the initial SoC boot, and hides
much of the hardware behind a protocol. This protocol is transported
using the SoC's mailbox hardware module.

Here, we add a very simplistic driver for the mailbox module, and define
a few structures for the property messages.

b33426caf6 mxs: spl_mem_init: Align DDR2 init with FSL bootlets source
Currently the following kernel hang happens when loading a 2.6.35 kernel from
Freeescale on a mx28evk board:

RPC: Registered tcp transport module.
RPC: Registered tcp NFSv4.1 backchannel transport module.
Bus freq driver module loaded
IMX usb wakeup probe
usb h1 wakeup device is registered
mxs_cpu_init: cpufreq init finished
...

Loading the same kernel using the bootlets from the imx-bootlets-src-10.12.01
package, the hang does not occur.

Comparing the DDR2 initialization from the bootlets code against the U-boot
one, we can notice some mismatches, and after applying the same initialization
into U-boot the 2.6.35 kernel can boot normally.

Also tested with 'mtest' command, which runs succesfully.

8f62ca646f usb: ehci: Support interrupt transfers via periodic list
Interrupt transfers aren't meant to be used from the async list
(the EHCI spec indicates trouble with low/full-speed intr on async).

Build a periodic list instead, and provide an API to make use of it.
Then, use that API from the existing interrupt transfer API.

This provides support for USB keyboards using EHCI.

Use timeouts to ensure we cannot get stuck in the keyboard scanning
if something wrong happens (USB device unplugged or fatal I/O error)

f7b4162eb1 usb:composite:fix Provide function data when addressing device with only one interface
This commit fixes problems with some non-standard requests send with
device address instead of interface address (bmRequestType.Receipent field).

This happens with dfu-util (debian version: 0.5), which address non standard
requests (like w_value=0x21 and bRequest=GET_DESCRIPTOR) to device.
Without this fix, the above request is STALLED, and hence causes dfu-util
to assume some standard configuration (packet size = 1024B instead of 4096B)
In turn it displays following errors:
Error obtaining DFU functional descriptor
Warning: Assuming DFU version 1.0
Warning: Transfer size can not be detected
...
Warning: Trying default transfer size 1024

This fix allows passing non-standard request to function setup code, where
it shall be handled.

Each architecture has its own asm/sections.h where symbols specifc to
that architecture can be added. For now everything except AVR32 just
includes the generic header.

The pinmux code issues a warning if the caller attempts to disable the
lock bit in a pinmux register, since this is impossible (once it's
locked, the only way to unlock it is to reset the device/pmt controller).

The I2C/DDC/CEC/USB macros expect a lock setting to be passed in,
and the previous setting of DISABLE caused the pinmux table parsing
code to issue the warning. Changing the lock bits in these table
entries to DEFAULT (i.e. don't touch it) fixes this.

These must be worked around in the bootloader, since in general, the

This code was taken from the Linux kernel, v3.8, arch/arm/mm/proc-v7.S,
and modified to remove the logic to conditionally apply the WAR (since we
know exactly which CPU we're running on given the U-Boot configuration),
and use r0 instead of r10 for consistency with the rest of U-Boot's

2) Not split the write to I2CSTAT into 2 steps in i2c read.
   According to the spec, we should write the combined M/R Start value to
   I2CSTAT after setting the slave address to I2CDS
3) Fix the mistake of making an equality check to an assignment.

case, we assume it is a size; otherwise we treat it as part of the

Also, add a space after the message fore easier reading,

ce0c1bc135 mmc:sdhci:fix: Change default interrupts enabled at SDHCI initialization
This patch changes sdhci_init()'s behavior to NOT enable all interrupt
sources by default. Moreover interrupt signaling has been disabled.

This patch do not enable interrupts which aren't served in u-boot
(they are defined at sdhci.h but NOT used elsewhere):
- SDHCI_INT_CARD_INSERT, SDHCI_INT_CARD_REMOVE, SDHCI_BUS_POWER,
  SDHCI_INT_CARD_REMOVE, SDHCI_INT_CARD_INT

Special care shall be put on SDHCI_INT_CARD_INT, which indicates
interrupt generated by SD card.
According to "SD Host Controller Simplified Spec. ver 3.00" when bit 8
(Card Interrupt Status Enable) at "Normal Interrupt Status Enable
Register" (offset 0x34) is set, the card interrupt detection is started.
Then eMMC card may cause the SD controller to set this bit and then this
interrupt is passed to booted OS and might cause kernel crash.

To sum up:
- Only enable interrupts, which are served at u-boot
- This cleanup as a side effect fixes SDHCI's CARD INTERRUPT problem at
  Linux kernel (versions 3.6+, sdhci controller)
- Keep masked bits at "Normal Interrupt Signal Enable Register" (0x38h)

ps on BSD hosts (like OS X) do not provide the --no-headers switch nor

get the PIDs of children in a platfrom independent manner.
Therefore detect the OS and decide upon that which way to go.

This patch makes the MAKEALL script cleanly stoppable on bare OS X when using
the parallel builds of targets.

Additionally this patch removes double call to grep by a single call to sed for
GNU style child PID detection.

a2681707b2 Feature Removal: disable "mtest" command by default
The "mtest" command is of little practical use (if any), and
experience has shown that a large number of board configurations
define useless or even dangerous start and end addresses.  If not even
the board maintainers are able to figure out which memory range can be
reliably tested, how can we expect such from the end users?  As this
problem comes up repeatedly, we rather do not enable this command by
default, so only people who know what they are doing will be
confronted with it.

As this changes the user interface, we allow for a grace period
before this change takes effect. For now, we make "mtest"
configurable through the CONFIG_CMD_MEMTEST variable, which is defined
in include/config_cmd_default.h;  we also add an entry to
doc/feature-removal-schedule.txt which announces the removal of this
default setting in two releases from now, i. e. with v2013.07.

581bb41980 lcd: add option for board specific splash screen preparation
Currently there is no logical place to put the code that prepares the
splash image data. The splash image data should be ready in memory
before bmp_display() is called, and after the environment is ready
(since lcd.c looks for the splash image in an address specified by
the environment variable "splashimage").

Our window of opportunity in board_init_r() is therefore: between
env_relocate() and bmp_display(), and from the available options
only the lcd related functions in drv_lcd_init() seem appropriate
for such lcd oriented code.

Add the option to prepare the splash image data in lcd_logo() right
before it is sent to be displayed.

3430e0bd2a mxs: mmc: spi: dma: Better wrap the MXS differences
This patch streamlines the differences between the MX23 and MX28 by
implementing a few helper functions to handle different DMA channel
mapping, different clock domain for SSP block and fixes a few minor
bugs.

First of all, the DMA channel mapping is now fixed in dma.h by defining
the actual channel map for both MX23 and MX28. Thus, MX23 now does no
longer use MX28 channel map which was wrong. Also, there is a fix for
MX28 DMA channel map, where the last four channels were incorrect.

Next, because correct DMA channel map is in place, the mxs_dma_init_channel()
call now bases the channel ID starting from SSP port #0. This removes the
need for DMA channel offset being added and cleans up the code. For the
same reason, the SSP0 offset can now be used in mxs_dma_desc_append(), thus
no need to adjust dma channel number in the driver either.

Lastly, the SSP clock ID is now retrieved by calling mxs_ssp_clock_by_bus()
which handles the fact that MX23 has shared SSP clock for both ports, while
MX28 has per-port SSP clock.

Finally, the mxs_ssp_bus_id_valid() pulls out two implementations of the
same functionality from MMC and SPI driver into common code.

resets the EMI block properly while also reverts the memory voltage bump.
The memory stability issues were caused by the EMI not being reset properly

it ought to run at.

62f7970a5a x86: Add error checking to x86 relocation code
This does not actually change normal behaviour, but adds a check that
should detect corruption of relocation data (e.g. by using BSS data
prior to relocation).

Also add additional debugging output when enabled.

During this investigation, two situations have been seen:
1. calculate_relocation_address():
	uintptr_t size = (uintptr_t)&__bss_end - (uintptr_t)&__text_start;

turns into
     111166f:	b8 83 c4 17 01       	mov    $0x117c483,%eax

whih is beyond the end of bss:

0117b484 g       .bss	00000000 __bss_end

Somehow the __bss_end here is 255 bytes ahead.

2. do_elf_reloc_fixups():

	uintptr_t size = (uintptr_t)&__bss_end - (uintptr_t)&__text_start;

Here the __text_start is 0 in the file:

 1111d9f:	bb a0 e0 13 01       	mov    $0x113e0a0,%ebx
1111da4:	81 ef 00 00 00 00    	sub    $0x0,%edi

As it happens, both of these are in pre-relocation code.

For these reasons we silent check and ignore bad relocations.

Rather than use strcasecmp() in the hash algorithm search, require the

d20a40de9d Roll crc32 into hash infrastructure
Add the CRC32 algorithm to the list of available hashes, and make
the crc32 command use hash_command(). Add a new crc32_wd_buf() to
make this possible, which puts its result in a buffer rather than
returning it as a 32-bit value.

Note: For some boards the hash command is not enabled, neither
are sha1, sha256 or the verify option. In this case the full
hash implementation adds about 500 bytes of overhead. So as a
special case, we use #ifdef to select very simple bahaviour in
that case. The justification for this is that it is currently
a very common case (virtually all boards enable crc32 but only
some enable more advanced features).

4213fc2913 sandbox: Add un/map_sysmen() to deal with sandbox's ram_buf
Sandbox doesn't actually provide U-Boot access to the machine's physical
memory. Instead it provides a RAM buffer of configurable size, and all
memory accesses are within that buffer. Sandbox memory starts at 0 and
is CONFIG_DRAM_SIZE bytes in size. Allowing access outside this buffer
might produce unpredictable results in the event of an error, and would
expose the host machine's memory architecture to the sandbox U-Boot.

Most U-Boot functions assume that they can just access memory at given
address. For sandbox this is not true.

Add a map_sysmem() call which converts a U-Boot address to a system
address. In most cases this is a NOP, but for sandbox it returns a
pointer to that memory inside the RAM buffer.

To get a U-Boot feature to work correctly within sandbox, you should call
map_sysmem() to get a pointer to the address, and then use that address for
any U-Boot memory accesses.

aa127df60e OMAP3: igep00x0: add missing include mach-types.h
Current '#if' directives (used in igep00x0.h config file) comparing MACH_TYPE
values in igep00x0.h doesn't work as expected. The comparision between
CONFIG_MACH_TYPE and MACH_TYPE_IGEP0020 is always true independent of the IGEP
machine configured.

For example, following directive

 if (CONFIG_MACH_TYPE == MACH_TYPE_IGEP0020)
    define something
 endif

Is always evaluated true although we configure u-boot for MACH_TYPE_IGEP0030.

The build doesn't shows any error so looks that both defines had always the same
value. Including the mach-types.h file sets properly the value of
MACH_TYPE_IGEPxxxx.

CPU:   Freescale i.MX6Q rev1.1 at 792 MHz
Reset cause: POR

So due to revC POR/watchdog circuitry whenever a watchdog occurs, it causes a POR.

Clearing the PDE - Power Down Enable bit of WMCR registers fixes the problem and
is also safe for all mx6 boards.

7c92c54075 imx: mx6q DDR3 init: Benefit from available CL = 7
All the users of mx6q_4x_mt41j128.cfg (DDR3-1333H Micron MT41J128M16HA-15E or SK
hynix H5TQ2G63BFR-H9C for i.MX6Q SABRE Lite, and DDR3-1600K Micron

  tRAS(min, DDR3-1600K) = 35 ns

MMDC1_MDCFG0.tCL should be set to 7 nCK, encoded as 0x4 in the bit-field
MMDC1_MDCFG0[3:0].

MR0.CL should be set as in MMDC1_MDCFG0.tCL, i.e. to 7 nCK, which is encoded

aa53149e11 imx: mx6q DDR3 init: Fix tXPR
MMDC1_MDOR.tXPR should be set as specified for the JEDEC DDR3 timing tXPR.

For all DDR3 speed bins:
  tXPR(min) = max(5 nCK, tRFC(min) + 10 ns)
  tRFC(2 Gb) = 160 ns

All the users of mx6q_4x_mt41j128.cfg have a 2-Gb density (Micron

MT41K128M16JT-125:K for i.MX6 SABRE SD).

Hence, MMDC1_MDOR.tXPR should be set to max(5 nCK, 170 ns), which is 170 ns
and 91 nCK at 532 MHz, encoded as 0x5A in the bit-field MMDC1_MDOR[23:16].

b19f57491a tegra: add SPI SLINK driver
Add driver for tegra SPI "SLINK" style driver.  This controller is
similar to the tegra20 SPI "SFLASH" controller.  The difference is
that the SLINK controller is a genernal purpose SPI controller and the
SFLASH controller is special purpose and can only talk to FLASH
devices.  In addition there are potentially many instances of an SLINK
controller on tegra and only a single instance of SFLASH.  Tegra20 is
currently ths only version of tegra that instantiates an SFLASH
controller.

This driver supports basic PIO mode of operation and is configurable
(CONFIG_OF_CONTROL) to be driven off devicetree bindings.  Up to 4
devices per controller may be attached, although typically only a
single chip select line is exposed from tegra per controller so in
reality this is usually limited to 1.

To enable this driver, use CONFIG_TEGRA_SLINK

For AM335X boards, such as the EVM and Bone Linux kernel fails to
locate the device tree blob on boot. The reason being is that
u-boot is copying the DT blob to the upper part of RAM when booting
the kernel and the kernel is unable to access the blob.
By setting the fdt_high variable to 0xffffffff (to prevent the copy)
the kernel is able to locate the DT blob and boot.

When ethaddr is not set in environment the MAC address is read
from efuse. The message was only printed in debug case, but this
message could be of interest for the ordinary user, so printf it.

d70f54808d omap4: allow the use of a plain text env file instead boot scripts
For production systems it is better to use script images since
they are protected by checksums and carry valuable information like
name and timestamp. Also, you can't validate the content passed to
env import.

But for development, it is easier to use the env import command and
plain text files instead of script-images.

Since both OMAP4 supported boards (Panda and TI SDP4430) are used
primarily for development, this patch allows U-Boot to load env var
from a text file in case that an boot.scr script-image is not present.

The variable uenvcmd (if existent) will be executed (using run) after
uEnv.txt was loaded. If uenvcmd doesn't exist the default boot sequence
will be started.

9d4f542123 OMAP3: igep00x0: add boot status GPIO LED
This patch adds an GPIO LED boot status for IGEP boards.

The GPIO LED used is the red LED0 while the Linux kernel
uses the green LED0 as the boot status.

By using different GPIO LEDs, the user can know in which
step of the boot process the board currently is.

77eea28074 OMAP3: use a single board file for IGEP devices
Even when the IGEPv2 board and the IGEP Computer-on-Module
are different from a form factor point of view, they are
very similar in the fact that share many components and how
they are wired.

So, it is possible (and better) to have a single board file
for both devices and just use the CONFIG_MACH_TYPE to make
a differentiation between each board when needed.

This change avoids code duplication by removing 298 lines of
code and makes future maintenance easier.

0f3073433c common/cmd_bootm.c: prevent running of subcommands before 'bootm start'
The execution order of the bootm subcommands is fixed.
Although here is a sanity check in the state machine
which should prevent running the subcommands in wrong
order but it does not catch all possible errors.

It is possible to run any subcommand without running
'bootm start' first which leads to unexpected behaviour.
For example, running 'bootm loados' without 'bootm start'
causes a hang:

    U-Boot> bootm loados
       XIP Invalid Image ... OK
    OK

Add a sanity check to 'do_bootm_subcommand' in order
to ensure that no subcommands can be executed before
'bootm start'.

After the patch running of any subcommand without running
'bootm start' will cause an error like this:

    U-Boot> bootm loados
    Trying to execute a command out of order
    bootm - boot application image from memory

    Usage:
    bootm [addr [arg ...]]
        - boot application image stored in memory
    ...

ac1048ae1c drivers/block/systemace - fixed data type in "systemace_read" to match prototype in "block_dev_desc_t"
Currently we have "unsigned long blkcnt" which is fine with
CONFIG_SYS_64BIT_LBA undefined because "lbaint_t" is basically the same
"unsigned long".
If CONFIG_SYS_64BIT_LBA gets defined "lbaint_t" is defined as "unsigned
long long".

Even though not many embedded systems have CONFIG_SYS_64BIT_LBA defined
it's good to have types in function implementation that match exactly
with prototypes.

16-bit data transfers. And in corresponding driver we need to implement
read/write of 16-bit data words properly for both modes of operation.

In existing code if width==8 both branches get executed which may cause
unexpected behavior of SystemAce controller.

Addition of "else" fixes described issue and execution is done as
expected for both (8-bit and 16-bit) data bus widths.

8568baed3b patman: Add support for settings in .patman
This patch adds support for a [settings] section in the .patman file.
In this section you can add settings that will affect the default
values for command-line options.

Support is added in a generic way such that any setting can be updated
by just referring to the "dest" of the option that is passed to the
option parser.  At the moment options that would make sense to put in
settings are "ignore_errors", "process_tags", and "verbose".  You
could override them like:

 [settings]
 ignore_errors: True
 process_tags: False
 verbose: True

The settings functionality is also used in a future change which adds
support for per-project settings.

from the CONFIG_SYS_MONITOR_BASE constant and from
the destination address. The resulting offset can
be used to adjust the gp pointer.

This approach makes the code a bit simpler because
it needs two instructions only.

025f2b3380 MIPS: simplify relocated _G_O_T_ address calculation
The difference between the address of the original
and the relocated _GLOBAL_OFFSET_TABLE_ is always
the same as the relocation offset.

The relocation offset is already computed and it is
available in the 's1/t6' register. Use that to adjust
the relocated _G_O_T_ address, instead of calculating
the offset again from the _gp value.

72bd83cd0a powerpc/t4240: Adding workaround errata A-005871
When CoreNet Fabric (CCF) internal resources are consumed by the cores,
inbound SRIO messaging traffic through RMan can put the device into a
deadlock condition.

This errata workaround forces internal resources to be reserved for
upstream transactions. This ensures resources exist on the device for
upstream transactions and removes the deadlock condition.

The Workaround is for the T4240 silicon rev 1.0.

Using environmental variable "ddr_interactive" to activate interactive DDR
debugging seomtiems is not enough. For example, after updating SPD with a
valid but wrong image, u-boot won't come up due to wrong DDR configuration.
By enabling key press method, we can enter debug mode to have a chance to
boot without using other tools to recover the board.

CONFIG_FSL_DDR_INTERACTIVE needs to be defined in header file. To enter the
debug mode by key press, press key 'd' shortly after reset, like one would
do to abort auto booting. It is fixed to lower case 'd' at this moment.

67d80c9f97 MIPS: start.S: don't save flush_cache parameters in advance
Saving the parameters in advance unnecessarily complicates
the code. The destination address is already saved in the
's2' register, and that register is not clobbered by the
copy loop. The size of the copied data can be computed
after the copy loop is done.

Change the code to compute the size parameter right
before calling flush_cache, and set the destination
address parameter in the delay slot of the actuall
call.

248fe03f53 MIPS: start.S: simplify relocation offset calculation
The current code uses four instructions and a
temporary register to calculate the relocation
offset and to adjust the gp register.

The relocation offset can be calculated directly
from the CONFIG_SYS_MONITOR_BASE constant and from
the destination address. The resulting offset can
be used to adjust the gp pointer.

This approach makes the code a bit simpler because
it needs two instructions only.

f321b0f99f MIPS: start.S: set sp register directly
The current code uses two instructions to load
the stack pointer into the 'sp' register.

This results in the following assembly code:

    468:   3c088040        lui     t0,0x8040
    46c:   251d0000        addiu   sp,t0,0

The first instuction loads the stack pointer into
the 't0' register then the value of the 'sp' register
is computed by adding zero to the value of the 't0'
register. The same issue present on the 64-bit version
as well:

    56c:   3c0c8040        lui     t0,0x8040
    570:   659d0000        daddiu  sp,t0,0

Change the code to load the stack pointer directly
into the 'sp' register. The generated code is functionally
equivalent to the previous version but it is simpler.

  32-bit:
    468:   3c1d8040        lui     sp,0x8040

  64-bit:
    56c:   3c1d8040        lui     sp,0x8040

14fdd1a8bf MIPS: start{, 64}.S: fill branch delay slots with NOP instructions
The romReserved and romExcHandle handlers are
accessed by a branch instruction however the
delay slots of those instructions are not filled.

Because the start.S uses the 'noreorder' directive,
the assembler will not fill the delay slots either,
and leads to the following assembly code:

  0000056c <romReserved>:
   56c:   1000ffff        b       56c <romReserved>

  00000570 <romExcHandle>:
   570:   1000ffff        b       570 <romExcHandle>

In the resulting code, the second branch instruction
is placed into the delay slot of the first branch
instruction, which is not allowed on the MIPS
architecture.

14e26bcfa7 mxs: ssp: Pull out the SSP bus to regs conversion
Create function which converts SSP bus number to SSP register pointer.
This functionality is reimplemented multiple times in the code, thus
make one common implementation. Moreover, make it a switch(), since the
SSP ports are not mapped in such nice linear fashion on MX23, therefore
having it a switch will simplify things there.

Instead of storing the computed line length in a local variable, store
it in the global lcd_line_length variable to make sure the LCD subsystem
can properly draw content for the display resolution.

This probably wasn't noticed yet because the only board where LCD
support is currently enabled is Seaboard, which runs at a 1366x768
resolution. As it happens this is the maximum resolution supported and
also the default that is used to initialize the framebuffer before the
configuration from DT is available.

3567e4ef11 MIPS: qemu-mips: add '-M mips' switch to the example usage command
Using the example command from the README file does
not work as expected. qemu shows a text similar to
the one below and it hangs.

    $ qemu-system-mips -L . -nographic
    Could not open option rom 'pxe-pcnet.rom': No such file or directory
    qemu-system-mips: pci_add_option_rom: failed to find romfile "vgabios-cirrus.bin"
    qemu: terminating on signal 15 from pid 19726

This happens because qemu emulates a Malta board by
default if the machine type is not defined explicitely
on the command line.

For a working test, the '-M mips' switch is required:

    $ qemu-system-mips -M mips -L . -nographic
    Could not open option rom 'vgabios.bin': No such file or directory

- CONFIG_SYS_GENERIC_BOARD
This selects the architecture-generic board system instead of the
architecture-specific board files. It is intended to move boards
to this new framework over time. Defining this will disable the
arch/foo/lib/board.c file and use common/board_f.c and
common/board_r.c instead. To use this option your architecture
must support it (i.e. must define __HAVE_ARCH_GENERIC_BOARD in
its config.mk file). If you find problems enabling this option on
your board please report the problem and send patches!
- CONFIG_SYS_SYM_OFFSETS
This is set by architectures that use offsets for link symbols

Generally U-Boot (and in particular the md command) uses
effective address. It is therefore not necessary to regard
U-Boot address as virtual addresses that need to be translated
to physical addresses. However, sandbox requires this, since
it maintains its own little RAM buffer which contains all
addressable memory. This option causes some memory accesses
to be mapped through map_sysmem() / unmap_sysmem().
