Thanks Carl-Daniel, I managed to do the commit. Unfortunately, SB600 does not support this option. Starting with SB800, the fast mode SPI writes can be used in addition to PrefetchEnSPIFromHost. SB900 has even more SPI improvement. Thanks, Scott -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
