My opinion is that option ROMs should not be needed, and that we have
code for basic init for all supported hardware in coreboot. (Set a
graphics mode or init a SCSI controller, but not spin up disks.)

Short term (a few years or so) I pretty much agree.
Long term I think I would like to set a graphics mode in coreboot.
Typically that isn't practical right now, but I would like to keep
the RageXL code in v3 too when the time comes. That will make us
think about where that type of init code fits in.
