Hi
David,
Have
verified and confirmed that coreboot process as well, it is
disabling the BIOS write protect and Enable Prefetching and Caching
as part of fast_spi_init().
Were you able to figure this one out? The snippet you showed is from fast_spi_init() which should get called once early on. It is possible that something later on calls fast_spi_enable_wp(), perhaps smihandler_soc_check_illegal_access().
