The AMCC Luan now uses the common 440SP(e) DDR SPD code for DDR
inititializition. This includes DDR auto calibration and support
for different DIMM modules, instead of the fixed setup used in
the earlier version.
This patch also enables the cache in FLASH for the startup
phase of U-Boot (while running from FLASH). After relocating to
SDRAM the cache is disabled again. This will speed up the boot
process, especially the SDRAM setup, since there are some loops
for memory testing (auto calibration).

Define CONFIG_PROG_SDRAM_TLB so that the TLB entries for the
DDR memory are dynamically programmed matching the total size
of the equipped memory (DIMM modules).

This patch fixes a problem that occurs when 2 DIMM's are
used. This problem was first spotted and fixed by Gerald Jackson
<gerald.jackson@reaonixsecurity.com> but this patch fixes the
problem in a little more clever way.
This patch also adds the nice functionality to dynamically
create the TLB entries for the SDRAM (tlb.c). So we should
never run into such problems with wrong (too short) TLB
initialization again on these platforms.
As this feature is new to the "old" 44x SPD DDR driver, it
has to be enabled via the CONFIG_PROG_SDRAM_TLB define.

As provided by the AMCC applications team, this patch optimizes the
DDR2 setup for 166MHz bus speed. The values provided are also save
to use on a "normal" 133MHz PLB bus system. Only the refresh counter
setup has to be adjusted as done in this patch.
For this the NAND booting version had to include the "speed.c" file
from the cpu/ppc4xx directory. With this addition the NAND SPL image
will just fit into the 4kbytes of program space. gcc version 4.x as
provided with ELDK 4.x is needed to generate this optimized code.

- fix logic error in image type handling
- make sure file system images (cramfs etc.) get stored in flash
with image header stripped so they can be mounted through MTD

This patch updates the recently added Katmai board support. The biggest
change is the support of ECC DIMM modules in the 440SP(e) SPD DDR2
driver.
Please note, that still some problems are left with some memory
configurations. See the driver for more details.

Some CPUs like PPC, BLACKFIN need sync() to ensure cfi flash write command
is fully finished. The sync() is defined in each CPU's io.h file. For
those CPUs which do not need sync for now, a dummy sync() is defined in
their io.h as well.

This patch enables the "new" get_dev() function for block devices
introduced by Grant Likely to be used on systems that still suffer
from the relocation problems (manual relocation neede because of
problems with linker script).
Hopefully we can resolve this relocation issue soon for all platform
so we don't need this additional code anymore.

Update / extend Software Update Mechanism for MCC200 board:
- Add support for rootfs image added. The environment variables
"rootfs_st" and "rootfs_nd" can be used to override the default
values of the image start and end.
- Remove excessive key check code.
- Code cleanup.
