That's not really good enough, IMHO.

So far, coreboot was always self-contained. It even goes so far as to
build its own toolchain.

Creating mandatory dependencies which may actually not always be
neccessary is simply poor software engineering, and not something
I think that we should be doing. Let's try to fix it!

Is there any technical reason *not* to decouple coreboot source from
vboot source completely?
