[coreboot] native video init question

[ron minnich]

ok, Nico, let's get this done :-)

I'm reviewing pending CLs from you, you'll need to fix the builds that
broke.

native graphics init has gone through several stages in linuxbios/coreboot,
in 2000, 2001, 2003, 2012, ...

I think the stuff you're pushing is some of the best we've seen.

Keep me posted on anything you need.

Thanks

ron
