As mentioned in your last email, the link was giving this list:
Target: e500v2 (I was able to reproduce with e500mc, e5500 targets as well).

So I tested these additional architectures and I confirm that they're
affected by this bug.
I also checked e500v1 (8540) and it failed.
There was no issue with e6500 so I think the bug is only affecting e5xxx
but I haven't tested all the powerpc architectures.
