Dear Heiko Schocher,
In message 4B1790D6.6030303@denx.de you wrote:
u-boot updates, before starting Linux, the memory node in the DTS. As this is a "standard" feature, move this functionality to the cpu.c file for mpc5xxx and mpc512x processors.

I generally agree with this patch, but...

Here we do some error checking, which is always a Good Thing (TM).

May I suggest to add the same error checking in these two files, then?
Thanks.
