nit: Technically, most of the stuff is useful on all coreboot devices,
not just Chromebooks. (Ideally we'd want to factor that out into a
separate drivers/firmware/coreboot, but it's a bit tricky because the
same memconsole frontend is used for both coreboot and a proprietary
Google server BIOS, so it's a little tricky to decide where everything
should go. Nobody had the time to go untangle it yet.)

GSMI is also used by Chromebooks AFAIK. (I think it's sort of become a
general coreboot interface by now as well, although the name still
says Google.)
