Add support for Motorola MPC8266ADS board

* Patch by Kyle Harris, 19 Feb 2003:
  patches for the Intel lubbock board:
  memsetup.S - general cleanup (based on Robert's csb226 code)
  flash.c - overhaul, actually works now
  lubbock.c - fix init funcs to return proper value

* Patch by Kenneth Johansson, 26 Feb 2003:
  - Fixed off by one in RFTA calculation.
  - No need to abort when LDF is lower than we can program it's only
    minimum timing so clamp it to what we can do.
  - Takes function pointer to function for reading the spd_nvram. Usefull
    for faking data or hardcode a module without the nvram.
  - fix other user for above change
  - fix some comments.

===========
U-Boot uses a 3 level version number containing a version, a
sub-version, and a patchlevel: "U-Boot-2.34.5" means version "2",
sub-version "34", and patchlevel "4".
The patchlevel is used to indicate certain stages of development
between released versions, i. e. officially released versions of
U-Boot will always have a patchlevel of "0".

More About U-Boot Image Types:
------------------------------
U-Boot supports the following image types:
"Standalone Programs" are directly runnable in the environment
provided by U-Boot; it is expected that (if they behave
well) you can continue to work in U-Boot after return from
the Standalone Program.
"OS Kernel Images" are usually images of some Embedded OS which
will take over control completely. Usually these programs
will install their own set of exception handlers, device
drivers, set up the MMU, etc. - this means, that you cannot
expect to re-enter U-Boot except by resetting the CPU.
"RAMDisk Images" are more or less just data blocks, and their
parameters (address, size) are passed to an OS kernel that is
being started.
"Multi-File Images" contain several images, typically an OS
(Linux) kernel image and one or more data images like
RAMDisks. This construct is useful for instance when you want
to boot over the network using BOOTP etc., where the boot
server provides just a single image file, but you want to get
for instance an OS kernel and a RAMDisk image.
"Multi-File Images" start with a list of image sizes, each
image size (in bytes) specified by an "uint32_t" in network
byte order. This list is terminated by an "(uint32_t)0".
Immediately after the terminating 0 follow the images, one by
one, all aligned on "uint32_t" boundaries (size rounded up to
a multiple of 4 bytes).
"Firmware Images" are binary images containing firmware (like
U-Boot or FPGA images) which usually will be programmed to
flash memory.
"Script files" are command sequences that will be executed by
U-Boot's command interpreter; this feature is especially
useful when you configure U-Boot to use a real shell (hush)
as command interpreter.

Correct me if I'm wrong, folks, but the way I understand it
is this: Using DCACHE as initial RAM for Stack, etc, does not
require any physical RAM backing up the cache. The cleverness
is that the cache is being used as a temporary supply of
necessary storage before the SDRAM controller is setup. It's
beyond the scope of this list to expain the details, but you
can see how this works by studying the cache architecture and
operation in the architecture and processor-specific manuals.
OCM is On Chip Memory, which I believe the 405GP has 4K. It
is another option for the system designer to use as an
initial stack/ram area prior to SDRAM being available. Either
option should work for you. Using CS 4 should be fine if your
board designers haven't used it for something that would
cause you grief during the initial boot! It is frequently not
used.
CFG_INIT_RAM_ADDR should be somewhere that won't interfere
with your processor/board/system design. The default value
you will find in any recent u-boot distribution in
Walnut405.h should work for you. I'd set it to a value larger
than your SDRAM module. If you have a 64MB SDRAM module, set
it above 400_0000. Just make sure your board has no resources
that are supposed to respond to that address! That code in
start.S has been around a while and should work as is when
you get the config right.

* Quote from 8260 UM (10.4.2 SDRAM Power-On Initialization, 10-35):
*
* "At system reset, initialization software must set up the
* programmable parameters in the memory controller banks registers
* (ORx, BRx, P/LSDMR). After all memory parameters are configured,
* system software should execute the following initialization sequence
* for each SDRAM device.
*
* 1. Issue a PRECHARGE-ALL-BANKS command
* 2. Issue eight CBR REFRESH commands
* 3. Issue a MODE-SET command to initialize the mode register
*
* Quote from Micron MT48LC8M16A2 data sheet:
*
* "...the SDRAM requires a 100uS delay prior to issuing any
* command other than a COMMAND INHIBIT or NOP. Starting at some
* point during this 100uS period and continuing at least through
* the end of this period, COMMAND INHIBIT or NOP commands should
* be applied."
*
* "Once the 100uS delay has been satisfied with at least one COMMAND
* INHIBIT or NOP command having been applied, a /PRECHARGE command/
* should be applied. All banks must then be precharged, thereby
* placing the device in the all banks idle state."
*
* "Once in the idle state, /two/ AUTO REFRESH cycles must be
* performed. After the AUTO REFRESH cycles are complete, the
* SDRAM is ready for mode register programming."
*
* (/emphasis/ mine, gvb)
*
* The way I interpret this, Micron start up sequence is:
* 1. Issue a PRECHARGE-BANK command (initial precharge)
* 2. Issue a PRECHARGE-ALL-BANKS command ("all banks ... precharged")
* 3. Issue two (presumably, doing eight is OK) CBR REFRESH commands
* 4. Issue a MODE-SET command to initialize the mode register
*
* --------
*
* The initial commands are executed by setting P/LSDMR[OP] and
* accessing the SDRAM with a single-byte transaction."
*
* The appropriate BRx/ORx registers have already been set when we
* get here. The SDRAM can be accessed at the address CFG_SDRAM_BASE.
