This patch now adds a new header file (asm-ppc/ppc4xx-sdram.h) for all
ppc4xx related SDRAM/DDR/DDR2 controller defines.
Signed-off-by: Stefan Roese <sr@denx.de>
This patch removes all SDRAM related defines from the PPC4xx headers
ppc405.h and ppc440.h. This is needed since now some 405 PPC's use
the same SDRAM controller as 440 systems do (like 405EX and 440SP).
It also introduces new defines for the equipped SDRAM controller based on
which PPC variant is used. There new defines are:
used on 405GR/CR/EP and some Xilinx Virtex boards.
used on 440GP/GX/EP/GR.
used on 440EPx/GRx.
used on 405EX/r/440SP/SPe/460EX/GT.

This patch (Part 2 of 2):
* Rolls up a suite of changes to enable correct primordial stack and
global data handling when the data cache is used for such a purpose
for PPC40x-variants (i.e. CFG_INIT_DCACHE_CS).
* Related to the first, unifies DDR2 SDRAM and ECC initialization by
eliminating redundant ECC initialization implementations and moving
redundant SDRAM initialization out of board code into shared 4xx
code.
* Enables MCSR visibility on the 405EX(r).
* Enables the use of the data cache for initial RAM on
both AMCC's Kilauea and Makalu and removes a redundant
CFG_POST_MEMORY flag from each board's CONFIG_POST value.
- Removed, per Stefan Roese's request, defunct memory.c file for
Makalu and rolled sdram_init from it into makalu.c.
With respect to the 4xx DDR initialization and ECC unification, there
is certainly more work that can and should be done (file renaming,
etc.). However, that can be handled at a later date on a second or
third pass. As it stands, this patch moves things forward in an
incremental yet positive way for those platforms that utilize this
code and the features associated with it.

Some 85xx chips use CCB as the base clock for the I2C. Some use CCB/2, and
some use CCB/3. There is no pattern that can be used to determine which
chips use which frequency, so the only way to determine is to look up the
actual SOC designation and use the right value for that SOC.
Update immap_85xx.h to include the GUTS PORDEVSR2 register.

This patch allows U-Boot to use buffered writes to the Spansion NOR
flash installed on this board, and eliminates long delays in network
transfers after the board startup.
Also modify flash layout to embed main and redundant environment

This patch removes the board dependent parts from
"drivers/mtd/dataflash.c".
Each board relying on this, will have the appropriate
code in a new file, "partition.c" in the board directory.
board Makefiles updated to use the file.
The dataflash partitions are aligned on sector/page boundaries.
The CONFIG_NEW_DF_PARTITION was used to create named partitions
This is now the default operation, and the CONFIG variable is removed.

Before new uImage code was merged, bootm code allowed for the kernel image to
get overwritten during decompresion. new uImage introduced a check for image
overwrites and refused to boot the image that got overwritten. This patch
restores the old behavior. It also adds a warning when the image overwriten is
a multi-image file, because in such case accessing componentes other than the
first one will fail.

This patch is based on the port by Mihai Georgian (see linkstation.c for
Copyright information) and implements support for LinkStation / KuroBox HD
and HG PPC models from Buffalo Technology, whereby HD is deactivated at
the moment, pending network driver fixing.
Notice to users: this is pretty much a barebone port. Support for network
on HG models is already in the U-Boot mainline, but you might also want
patches to switch fan / phy modes depending on the negotiated ethernet
parameters. This patch also doesn't support console switching, booting EM
mode, Buffalo specific ext2 magic number. So, if you want to use any of
those, you need additional patches. Otherwise this patche provides a fully
functional u-boot with a network console on your system.

Adds Support for Altera's Stratix II.
Within your board specific init file you will have to call
1. fpga_init (/* relocated code offset. usually => */ gd->reloc_off);
2. fpga_add (fpga_altera, (Altera_desc*)&altera_desc);
Altera_desc* contines (for example):
{
Altera_StratixII, /* part type */
passive_serial, /* interface type */
1, /* bytes of data part can accept */
(void *)(&funcs), /* interface function table */
0L, /* base interface address */
0 /* implementation specific cookie */
}
funcs is the interface. It is of type altera_board_specific_func.
It looks like this:
altera_board_specific_func func = {
pre_fn,
config_fn,
status_fn,
done_fn,
clk_fn,
data_fn,
abort_fn,
post_fn,
};
you will have to implement these functions, which is usually bit

This patch fixes eeprom page size so that you can now write more than
64 bytes at a time.
It also makes the board take MAC addresses, if found, from EEPROM.
User should place up to 4 addresses at offset 0x7f00, for
eth{,1,2,3}addr. Any unused addresses should be zero. This group of
four six-byte values should have it's CRC at the end. crc32 and
eeprom commands can be used to accomplish this.
If CRC fails, MAC addresses come from the environment. If CRC
succeeds, the environment is overwritten at startup.
