Thanks for all the valuable input. So this is what I have checked so far.
Until now the behaviour is still exactly as described in the first post.

It sure looks like an mpc8313 problem I once looked into
for quite some time. The solution was:

It could also be your DDR RAM not properly functioning. You
can let u-boot test it with the POST MEM test (which happens
before relocation

Hi all,
I'm currently seeing a weird heisen-bug kind of problem on a mpc8313-based
board with large page NAND flash. The problem happens in u-boot-spl in
relocate_code. When I set a breakpoint after the first cycle of
...cpu/mpc83xx/start.S
relocate_code:
1: lwzur0,4(r8)
stwur0,4
8 matches
