There is no point in disabling the icache on 7xx/74xx/86xx parts and not
also flushing the icache. All callers of invalidate_l1_instruction_cache()
call icache_disable() right after. Make it so icache_disable() calls
invalidate_l1_instruction_cache() for us.
Also, dcache_disable() already calls dcache_flush() so there is no point
in the explicit calls of dcache_flush().

Incorrect CFG_HZ value, change 1000000 to 1000.
Rename #waring to #warning. RAMBAR1 uses twice
in start.S, rename the later to FLASHBAR. Insert
nop for DRAM setup. And, env_offset in linker file.

Note that with older board revisions, NAND boot may only work after a
power-on reset, and not after a warm reset. I don't have a newer board
to test on; if you have a board with a 33MHz crystal, please let me know
if it works after a warm reset.

Here comes a trivial patch to cpu/arm926ejs/davinci/nand.c. Unfortunately I
don't have hardware handy so I can not test it at the moment but changes are
rather trivial so it should work. It would be nice if somebody with a
hardware checked it anyways.

This patch changes the 4xx NAND driver ndfc.c to match the new
infrastructure from the updated NAND subsystem. This NAND
subsystem was recently synced again with the Linux 2.6.22 MTD/NAND
subsystem.
Tested successfully on AMCC Sequoia and Bamboo.

A lot changed in the Linux MTD code, since it was last ported from
Linux to U-Boot. This patch takes U-Boot NAND support to the level
of Linux 2.6.22.1 and will enable support for very large NAND devices
(4KB pages) and ease the compatibility between U-Boot and Linux
filesystems.
This patch is tested on two custom boards with PPC and ARM
processors running YAFFS in U-Boot and Linux using gcc-4.1.2
cross compilers.
MAKEALL ppc/arm has some issues:
* DOC/OneNand/nand_spl is not building (I have not tried porting
these parts, and since I do not have any HW and I am not familiar
with this code/HW I think its best left to someone else.)
Except for the issues mentioned above, I have ported all drivers
necessary to run MAKEALL ppc/arm without errors and warnings. Many
drivers were trivial to port, but some were not so trivial. The
following drivers must be examined carefully and maybe rewritten to
some degree:
cpu/ppc4xx/ndfc.c
cpu/arm926ejs/davinci/nand.c
board/delta/nand.c
board/zylonite/nand.c

This is needed because we will be possibly be locating
devices at physical addresses above 32bits, and the asm
preprocessing does not appear to deal with ULL constants
properly. We now call write_bat in lib_ppc/bat_rw.c.

Correct the mx31_gpio_mux() function to allow changing all i.MX31 IOMUX
contacts instead of only the first 256 ones as is the case prior to
this patch.
Add missing MUX_* macros and update board files to use the new macros.

On ADS5121 when booting linux the following errors are seen:
Unable to update property /soc5121@80000000:bus-frequency, err=FDT_ERR_NOTFOUND
Unable to update property /soc5121@80000000/ethernet@2800:local-mac-address, err=FDT_ERR_NOTFOUND
Unable to update property /soc5121@80000000/ethernet@2800:address, err=FDT_ERR_NOTFOUND
This is caused by ft_cpu_setup trying to deal with
both old and new soc node naming. This patch
fixes this by being smarter about what to
fixup.
Also do soc node fixups by compatible instead of by path.
A new board config called OF_SOC_COMPAT defined
to be "fsl,mpc5121-immr" replaces the old
OF_SOC node path that was defined to be "soc@80000000".
Old device trees still work, but the compatiblity
is conditional on CONFIG_OF_SUPPORT_OLD_DEVICE_TREES
which is on by default in include/configs/ads5121.h.

The Hammerhead platform is built around a AVR32 32-bit microcontroller
from Atmel. It offers versatile peripherals, such as ethernet, usb
device, usb host etc.
The board also incooperates a power supply and is a Power over Ethernet
(PoE) Powered Device (PD).
Additonally, a Cyclone III FPGA from Altera is integrated on the board.
The FPGA is mapped into the 32-bit AVR memory bus. The FPGA offers two
DDR2 SDRAM interfaces, which will cover even the most exceptional need
of memory bandwidth. Together with the onboard video decoder the board
is ready for video processing.

This patch fixes a problem with incorrect MODTx (On Die Termination)
setup for a configuration with multiple DIMM's and multiple ranks.
Without this change Katmai was unable to boot Linux with DDR2 frequency
>= 533MHz and mem>=3GB. With this patch Katmai successfully boots Linux
with DDR2 frequency = 640MHz and mem=4GB.

The L2 size detection code was a bit confusing and we kept having to add
code to it to handle new processors. Change the sense of detection so we
look for the older processors that aren't changing.
Also added support for 1M cache size on 8572.

Some boards that have external 16550 UARTs don't have a direct
tie between bi_busfreq and the clock used for the UARTs. Boards
that do have such a tie should set CFG_NS16550_CLK to be
get_bus_freq(0) -- which most of them do already.

With a page size of BOOKE_PAGESZ_16M, both the real and effective
addresses must be multiples of 16MB. The hardware silently truncates
them so the code happens to work. This patch clarifies the situation
by establishing addresses that the hardware doesn't need to truncate.
