Wolfgang,

please find attached a patch for the cpu/ppc4xx/spd_sdram file. The ECC configuration code in function spd_sdram is changed so that 72 bit ECC DIMM's are used in non-ECC mode. Using those DIMM's in ECC mode doesn't work on the walnut board. If working, it would make probably no sense, because only the half of the DIMM size can be used in ECC mode. CFG_MONITOR_LEN in include/configs/WALNUT405.h was changed to 256, because 192 was too small for the configuration provided with u-boot-0.3.0

Maybe the patch is of some use for the project.

Best regards,

Thomas Schäfer
