Please don't assume. When something is unclear, creating an
opportunity for assumption, then documentation and/or code should be
improved, so that no assumption is needed.

It's quite natural since coreboot is not equipped to run option ROMs;
it does not have any BIOS interrupt services, which option ROMs
typically rely on, since option ROMs are a BIOS concept.

Which option ROM option are you talking about? Please be specific,
use the CONFIG_ name. And since discussion now covers both coreboot
and SeaBIOS it helps further if you specify which project the
particular option is in.

There are use cases both for coreboot running option ROMs and SeaBIOS
running option ROMs, regardless of how SeaBIOS was started.

I tend to agree that coreboot should default to not run option ROMs,
and possibly the SeaBIOS configuration generated by the coreboot
build files should enable SeaBIOS running the option ROM in that
case, but it's not trivial to find a way that makes sense for every
case. Feel free to think about it and propose an improvement, it can
probably be better than it is at the moment.
