This patch adds the "ecctest" command to test and simulate ECC errors
(single bit and/or double bit) while running from SDRAM. Currently only
the IBM DDR2 controller is supported (405EX, 440SP(e), 460EX/GT).
This is done by copying and calling functions, modifying the SDRAM
controller operation mode, in internal SRAM/OCM.
For correctable ECC errors (single bit) only the status will be printed
since the DDR2 controller doesn't provide the faulting address:
=> ecctest 1000000 1
Using address 01000000 for 1 bit ECC error injection
ECC: Correctable error
Uncorrectable ECC errors (double bit) will also display the faulting
address:
=> ecctest 1000000 2
Using address 01000000 for 2 bit ECC error injection
ECC: Uncorrectable error at 0x0001000000
To enable this "ecctest" function you need to define CONFIG_CMD_ECCTEST
in the board config header.
Tested on katmai and t3corp.

As discussed on the list, move "arch/ppc" to "arch/powerpc" to
better match the Linux directory structure.
Please note that this patch also changes the "ppc" target in
MAKEALL to "powerpc" to match this new infrastructure. But "ppc"
is kept as an alias for now, to not break compatibility with
scripts using this name.
