I finaly identified the issue. It is a long lasting bug that was 
introduced when powerpc was migrated to generic board. The powerpc 
version of board_init_f() was not using boot_flags and the asm callers 
didn't take care of it.

But generic version of board_init_f() uses it, and it is random.

Everything goes well when boot_flags are set to 0.

I will send a patch shortly to fix it.
