That may or may not be a problem for startup code. if we do our jobs right, and use cbfs to hold the ROMSTRAP, we ought to be able not to do use TOP-127 to TOP-16. We can count on the hardware vendors to come up with new challenges, so I no longer believe anything is safe :-) ron -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
