This makes no sense to me  - especially as it works on all other
systems.

Well, you mentioned you were using a MPC5125 processor which is not
supported in mainline U-Boot, and which is known to have enough
differences in it's register layout that anything might be the cause
for such issues.

Is it correct to assume that you have a _lot_ of local modifiucations
in your tree?  I bet the problem lies there...

Best regards,

Wolfgang Denk
