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).

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.

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.

- 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 adds support for multiple I2C busses on the PPC4xx
platforms. Define CONFIG_I2C_MULTI_BUS in the board config file
to make use of this feature.
It also merges the 405 and 440 i2c header files into one common
file 4xx_i2c.h.
Also the 4xx i2c reset procedure is reworked since I experienced
some problems with the first access on the 440SPe Katmai board.

Change the xilinx device drivers and board code to include config.h
instead of xparameters.h directly. config.h always includes the
correct xparameters file. This change reduces the posibility of
including the wrong file when adding a new xilinx board port

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.

Now the AMCC eval boards Yosemite (440EP) and Yellowstone (440GR)
share one config file and all board specific files. This way we
don't have to maintain two different sets of files for nearly
identical boards.

currently sectors 0-3. Sector 3 does not need to be protected, though
(U-boot occupies sectors 0-1 and the environment sector 2). This commit
fixes this, i.e., only sectors 0-2 are protected.

Now the board revision and the current PCI bus speed are printed after
the board message.
Also the EBC initialising is now done via defines in the board config
file.
