skylake: Move ACPI init to SOC instead of mainboard
Move some remaining ACPI init code to the SOC instead of being done in each mainboard: - acpi_create_gnvs is now a local function - add a weak acpi_mainboard_gnvs() that can be used for mainboards to override or set additional NVS - add acpi_fill_madt() function for skylake - remove acpi_create_serialio_ssdt() function as it is unused BUG=chrome-os-partner:40635 BRANCH=none TEST=emerge-glados coreboot Change-Id: I52225e8d38ed846c29d44872e3f4d6ebaf4a7e52 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Original-Commit-Id: c717bb418a0cb6002582572632e42b44b473f718 Original-Change-Id: I0910ac8ef25de265ae1fde16b68f6cbacedb4462 Original-Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Original-Reviewed-on: https://chromium-review.googlesource.com/297800 Original-Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-on: http://review.coreboot.org/11581 Reviewed-by: Alexandru Gagniuc <mr.nuke.me@gmail.com> Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>
