It looks like you have some memory corruption between here...

Scott,
are you talking about a possible hardware problem or misbehaving code ?
Either. The same OF call is done in both places with the same
argument, but is getting different results.
Does it look like something gets overwritten during initrd
extraction/movement ?
Don't know.
The system has 512MB RAM which means that we need 2 BAT regs to map
the memory. I've found comments in Freescale u-boot header files that
currently a max of 256MB is supported. I never understood why ? Could
this problem be related to this ?
Kim's probably be the best one to answer u-boot questions.
-Scott
Scott + Kim,
as mentioned before I have re-built u-boot with the following
modifications :
- Reduce Memsize from 512 to 256MB
- Skipped 2nd BAT setup
dtb looks the same but memory size set to 256MB.
System boots fine - this is weird !
I'm not really familiar with the powerpc tree of the kernel and far out
of sync with the current development.
Could you have a look at this ?
Any ideas right now ?
Thanks,
Andre
