Re: [PATCH V2] video: implement a simple framebuffer driver

I think it would be reasonable to have a restriction of only a single
bootfb instance, so one could just use static global variables/funcs to
manage the hand-over.

All this, of course, presumes that nobody else than fbcon is using the
fb. But I think it's also a reasonable restriction that the fb device is
not used (mmapped) by anyone.

We already have this on x86, though the handover isn't great,

FBINFO_MISC_FIRMWARE flag, and the aperture tracking stuff.
