I think long-term we want a (runtime/CMOS) option for coreboot
to enable/disable ROM protection. For now, I guess every chipset does
a different thing and/or doesn't explicitly protect or unprotect
the ROM at all.

As a safe default I think disabling the ROM write access is the best thing
to do from a user's point of view.

Sure, flashrom does that. And for other chipsets where we might write-protect
the ROM later we also have flashrom chipset support. I cannot think
of any chipset where we have coreboot support but no flashrom support
(even for CK804 and MCP55 we have).
