intel/common/block/scs: Add ability to send early CMD0, CMD1
In order to improve boot time with emmc, add ability to send CMD0 and CMD1 early in romstage. This way, by the time system boots to payload, we are ready to continue with emmc setup and we don't need to send CMD0 in payload again, and wait for card to reset and be ready. BUG=b:78106689 TESTS = Boot to OS Force early_mmc_wake_hw() to return error, recover in payload Force an error in payload, make sure system can recover/boot Change-Id: I3488b077bf5100a1e0f2c879fb1436105607d25e Signed-off-by: Bora Guvendik <bora.guvendik@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/25068 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Lijian Zhao <lijian.zhao@intel.com>
