That is correct. Some boards(85xx) seem to have bss_start at 0 sometimes
and that won't play nice with this patch. Peter was looking into this but
seems like he isn't finished yet.

Also, I have been looking at moving this relocation to C-code and it isn't
quite ready yet. What is left is to modify all ppc boards to use this new C-code
