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
blocks in the U-Boot image.

Currently U-Boot crashes on sequoia board in CPU POST if
cache is enabled (CONFIG_4xx_DCACHE defined). The cache
won't be disabled by change_tlb before CPU POST because
there is an insufficient adress range check since
CFG_MEM_TOP_HIDE was introduced. This patch tries to fix
this problem.

Current assembler codes are inconsistent in the way of register jump
instruction usage; some use jr, some use j. Of course GNU as allows both
usages, but as can be expected from `Jump Register' the mnemonic `jr' is
more intuitive than `j'. For example, Linux doesn't have `j <reg>' usage
at all.

MC13783 is a multifunction IS with an SPI interface to the host. This

This is an SPI driver for i.MX and MXC based SoCs from Freescale. So far
only implemented and tested on i.MX31, can with a modified register layout
and definitions be used for i.MX27, I think, MXC CPUs have similar SPI
controllers too.

Split the arch-specific logic out of the common go code and into a dedicated
weak function called do_go_exec() that lives in cpu directories. This will
need review from i386/nios people to make sure I didn't break them.
Change the bootelf setup function into a dedicated weak function called
do_bootelf_exec. This way ports can control the behavior however they
like before/after calling the ELF entry point.

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.

There are two NAND entries with ID 0xDC and this obviously causes problems.
In the kernel, they punted the first entry, so we should do the same.

Before the first call of ide_reset(), the level of the IDE reset
signal on the TQM5200 is low (reset asserted). This patch sets the
default value to high (reset not asserted).
Currently this patch fixes no real problem, but it is cleaner to
assert the reset signal only on demand, and not permanently.

According to the ata (ata5) specification the RESET- signal
shall be asserted for at least 25 us. Without this patch,
the RESET- signal is asserted on some boards for only < 1 us
(e. g. on the TQM5200). This patch adds a general delay of
25 us to the RESET- signal.
Without this patch a Platinum 4 GiB CF card is not recognised
properly on boards with a TQM5200 (STK52xx, TB5200).
