Nico Huber has uploaded this change for review. ( https://review.coreboot.org/22348 Change subject: ichspi: Disable software sequencing by default for Skylake ...................................................................... ichspi: Disable software sequencing by default for Skylake Skylake is a mess, especially with coreboot. We have now a present and configured software sequencing interface with SCGO supposedly being readonly (Apollo Lake has that feature and a strap documented, Skylake behaviour might be the same). As we can't easily check if it's read- only, just enable hardware sequencing by default (even if the software sequencing interface seems usable).
