Commit f369e1564c turned those off because the SPL size grew too
large. It also argued that those boards would never support EFI booting.
The former is correct, therefore keep CONFIG_SPL_EFI_PARTITION off.
CONFIG_SPL_ISO_PARTITION is default off. What is not correct is that
those boards are limited to legacy boot - you just need a hybrid
partition table to make both the bootrom and UEFI happy.

By default, the de0_nano_soc used raw sectors, but the address became
invalid due the raw-mode refactorings. With loading via partition type
fixed, we can switch to that mode which is in line with what the ROM
loader does.

If U-Boot is located on MMC, SPL and U-Boot proper are glued together.
More precisely, SPL is stored 4 times. Take this and its padding into
account and adjust sector number via board_spl_mmc_get_uboot_raw_sector.

This function and the sector parameter evolved over the time. By now,
sector is influenced by spl_mmc_get_uboot_raw_sector which allows to
adjust the read sector with an offset that U-Boot proper may have inside
the partition. That used to work by chance if both
CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_USE_SECTOR and
CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_USE_PARTITION were enabled. Since

Quentin Schulz <foss+uboot@0leil.net> says:
This does a bit of "cleanup" by reusing constants for some FIT
properties instead of having the same string in multiple places.
Additionally, this adds a new constant for the compatible property in
FIT configuration nodes[1] which is useful for FIT images with multiple
FIT configuration nodes to support multiple devices in the same blob.
U-Boot will try to figure out which node to select based on that
compatible[2].
However, if this property is missing (and the first blob in the fdt
property of the configuration node is uncompressed), the compatible from
the root node of the associated kernel FDT will be used for the
autoselection mechanism. For now, I only print the property if it
exists, but maybe it'd make sense to expose the fallback one if it's
missing. I guess we can implement that later on if desired.

Fit conf node may have a compatible property[1] which stores the
compatible of the first blob in the fdt property of the node. This can
be used to automatically select the proper conf node based on the
compatible from the running U-Boot (matching the former's compatible
with the latter)[2].
This brings the ability to mkimage/dumpimage to print the compatibles of
the configuration node(s). U-Boot CLI commands such as iminfo also see
this addition to their output.

We are trying to get rid of the legacy LED API and this is one of the
last users.
As far as I understood from the code, only one LED is controllable and
it is a GPIO led. When initializing the LED, it is always enabled
regardless of the passed argument, same for the mask.
In addition, the LED is used as a BOOT LED.
To keep the same behavior, a GPIO driver should be written, then add a
gpio-leds node which makes use of a GPIO from said driver, add the
/options/u-boot/boot-led property pointing at this new GPIO LED node and
then enable CONFIG_LED as well as CONFIG_LED_BOOT. This should result in
the same behavior using the modern framework.

The usage of fdt_fixup_reserved is repeated for ATF and OP-TEE for
multiple platforms, this patch creates a single fdt API for fixing up
the reserved-memory node with added error handling.
All k3 platforms already share a common tispl template which ensures
binaries are loaded as per the respective CONFIG_*_LOAD_ADDR. And the
provided new_size for the fixup is overridden by the size from fdt node
anyways. This allows for safe abstraction of the reserved memory fixups
for all current platforms.
fdt_fixup_reserved now abstracts the ATF and OP-TEE fixups by calling
the renamed static fdt_fixup_reserved_memory function with the required
parameters.

In the last message sent in rockchip_i2c_xfer, the controller is
disabled (see rk_i2c_disable() in rk_i2c_read()/rk_i2c_write()), then
the STOP condition is sent (see rk_i2c_send_stop_bit() in
rockchip_i2c_xfer()) and the controller is disabled once again (see
rk_i2c_disable() right after).
The issue is that re-enabling the controller just to send the STOP
condition doesn't work. When, the controller is disabled, the SCL and
SDA lanes are not driven anymore and thus enter the idle mode where they
are kept high by the external HW pull-up. To send a STOP condition, one
needs to drive the SDA line so that a rising edge happens while SCL is
high. Experimentally (on PX30 and RK3399), when enabling the controller
to send a STOP condition after it's been disabled, the controller only
drives the SDA line to trigger the rising edge for the STOP condition,
leaving SCL undriven (and thus, high). This means, that because SDA is
high before this happens and that we need a rising edge, the controller
drives the SDA line low and then releases it, meaning we trigger a START
condition followed by a STOP condition:
SCL
_________
_____...
__ _____
_____... \/
SDA
^ STOP
^ START
This is illegal in I2C protocol[1]:
5. A START condition immediately followed by a STOP condition (void
message) is an illegal format. Many devices however are designed to
operate properly under this condition.
My guess is that the I2C controller IP knows that it makes only sense to
send a STOP condition after a START condition, meaning the controller is
already driving the SCL line low and neither the device nor controller
drive the SDA line after the last ACK/NACK as there's no need to, then
it needs to drive SDA, release SCL to make it high and then release the
SDA line. However, after it's been disabled, the SCL is already released
so the controller only essentially drives SDA and then releases it.
It happens that this seems to be breaking the SE050 Secure Element after
a few transfers in the middle of a transfer where it starts clock
stretching the bus forever. It may be related to Errata 3.2[2] but the
description of the setup isn't an exact match to the current situation.
It seems to be required to disable the I2C controller between messages
as the Linux kernel states that "The HW is actually not capable of
REPEATED START. But we can get the intended effect by resetting its
internal state and issuing an ordinary START.". Between messages, this
logic seems fine as I get an Sr (repeated START condition) before
starting the next message in the transfer without a STOP condition.
However, we should NOT disable the controller after the last message in
the transfer otherwise we do this illegal START condition followed by
the STOP condition, hence the added check.

I2C_CON_STOP is a flag to be used for the con register, where it is bit
4 to send the STOP condition.
To enable the interrupt the controller sends to tell it's finished
sending the STOP condition, it's the ien register at bit 5.
Let's use the proper offset.
My hunch is that enabling the interrupt is useless as the interrupt
status register is always up-to-date and enabling the interrupt is just
so that the interrupt is available via the GIC. However, U-Boot has no
interrupt support and the logic was working well before this patch. This
is just so people aren't side-tracked when debugging I2C issues on

The BootROM in Rockchip SoCs will enter maskrom mode when boot firmware
cannot be found in nand/spi/mmc storage.
In maskrom mode the USB OTG port can accept one of two custom commands.
Initially a 0x471 command to load TPL into SRAM. After TPL has been
executed and it has returned back-to-BROM, a 0x472 command to load SPL
into start of DRAM.
Add two binman images that can be used to RAM boot from maskrom mode:
- u-boot-rockchip-usb471.bin that contains TPL to init DRAM.
- u-boot-rockchip-usb472.bin that contains SPL and the normal FIT
payload with i.e. U-Boot proper, TF-A and FDT.
A config fragment rockchip-ramboot.config can be used to enable building
of these two binman images, e.g.:
make generic-rk3588_defconfig rockchip-ramboot.config
These binman images can be used with the proprietary rkbin boot_merger
tool to create a special loader image that can be used with tools such
as rkdeveloptool or rockusb tools to RAM boot from maskrom, e.g.:
Create loader image:
$ ../rkbin/tools/boot_merger ./RK3588MINIALL.ini
Boot from maskrom:
$ rkdeveloptool db u-boot-rockchip-rk3588-loader.bin
or
$ rockusb download-boot u-boot-rockchip-rk3588-loader.bin
Another option that does not require use of proprietary tools is using
open source tools such as rkflashtool or rkusbboot that can load the
binman images directly without any need to first create a special loader
image to RAM boot from maskrom, e.g.:
$ rkflashtool l < u-boot-rockchip-usb471.bin
$ rkflashtool L < u-boot-rockchip-usb472.bin

While this change was intended to fix a mistake in the code, of calling
the ERR_PTR macro but not making use of the result, it seems that
functionally platforms depend on the loop not existing here. The TI K3
families of platforms for example were broken by this commit.
This reverts commit fe780310cf.
