I believe the main thing that came out of this was the reminder that
there was an even older attempt by U-Boot to have such a mechanism, and
that at the time getting the work accepted in Linux faced some hurdles
or another.

That said, I too agree with taking what's already a de facto standard,
the coreboot logging, and expand on it as needed.
