[PATCH] Update AMCC Katmai 440SPe eval board support
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.
