Well, in a way yes. I initially thought that all those warnings where
normal, but indeed not. We were missing some things in powerpc linker 
script, and most likely some sections ended up in the wrong place.

Last week I tested on an 8xx and it was booting without any issue.
I tested today on an 83xx and it was not booting.

I will soon send new patches with the fixes in the linker scripts.

Thanks for your help
Christophe
