[coreboot] User interface on coreboot

[ron minnich]

The plan, long ago, when it was still linuxbios, was that linux would
be the basis of interaction. Back then we were booting linux out of
flash faster than any known bios would put up a screen. We had tools
(rdcmos etc.) to manipulate cmos. We even had commands to control
overclocking from linux.

So the interaction path was the linux shell.

Then the bloat monster hit and the idea of linux as the firmware died.
