I'd prefer you use spaces for formatting (so that they look the same
regardless of tabstop size), but no matter what you should be consistent
(see OP_RFI vs XOP_RFI).

Actually, right now I'm wondering why rfi emulation isn't in the shared
emulation code. Do you see any core-specific issues there? Same with
wrtee* and m*msr.

I bet I was thinking "we should have booke_emulate.c in the future" when
I moved the 44x code. What do you think about that?
