Scratch that - with my proposed x86 changes, I do not need to pass a gd_t*

Plus, moving init sequence into board_init_f() before relocation means I
loose to ability to 'load anywhere' (which is not a totally disastrous
loss) so I don't need load_offset any more. So I can still pass bootflag
for warm/cold boot indication

I still think we need to clean-up microblaze, nios2 and sh
