The CAR code needs to clean up and switch back to normal operation. You could argue that it doesn't need to switch back but that is risky and might cause problems later in boot. It would probably be safe to move it to low memory instead of up high. Marc -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
