Question is, what is this "case"? Chris, what is your motivation for the
coreboot port?

LinuxBoot is an ambiguous term. What Ron and Philipp suggest here is
taking an existing UEFI, strip it down to something as light as core-
boot and plug the Linux kernel in. If you just want to get rid of the
bloated, often bug haunted, user visible parts of UEFI, this is a
good way to achieve it. If you want more control over the earlier,
lower level parts of the boot process, coreboot is the way to go, IMO.

The convenient trick of UEFI/LinuxBoot is that you don't have to care
about any mainboard specific things, if somebody else already ported
UEFI for your board. And other than the name suggests, you can boot
any other OS*, the Linux in LinuxBoot is just a fancy boot loader.
