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.

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 adds support for the DDR2 controller used on the
440SP and 440SPe. It is tested on the Katmai (440SPe) eval
board and works fine with the following DIMM modules:
- Corsair CM2X512-5400C4 (512MByte per DIMM)
- Kingston ValueRAM KVR667D2N5/512 (512MByte per DIMM)
- Kingston ValueRAM KVR667D2N5K2/2G (1GByte per DIMM)
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.

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.

buffer pointers
Block device read/write is anonymous data; there is no need to use a
typed pointer. void * is fine. Also add a hook for block_read functions

Some boards that can have more than 768MBytes of SDRAM need to
set "initrd_high", so that the initrd can be accessed by the
Linux kernel.

When PCI PNP is enabled the pci pnp configuration routine is called
which sets the PCI_CACHE_SIZE_LINE to 8. This seems to generate some
problems with some PCI cards. For now disable the PCI PNP configuration.

The config file now handles the 2nd target, the Rainier (440GRx)
evaluation board better. Additionally the PPC input clock was
adjusted to match the correct value of 33.0 MHz.

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.

"mii device" results in "Unexpected exception"). Fixing this properly
requires some clean-up in the FEC drivers infrastructure for ColdFire, so
this commit disables MII commads for now.
