I've gone and changed them to printf's, and a lot of stuff I would
expect to see, I don't. On tegra, can you do a before/after debug build
and see what board_init_f shows?

Actually, what I'm seeing is more "is this generic or ARM or x86 or PPC
code?" There's a lot of that merging that needs doing still and I guess
that's part of the mess.

I'll post patches for omap4_panda and then hopefully omap3_beagle, or
die trying :)
