soc/intel/alderlake: Inform user of memory training
If memory training is going to happen and early graphics is supported by the mainboard, an on-screen text message is displayed to inform the end user. Memory training can take a while and an impatient end user facing a black screen for a while may reset the device unnecessarily. BUG=b:252792591 BRANCH=firmware-brya-14505.B TEST=On screen text message during MRC training observed on skolas Change-Id: I4ea15123eed1a4355c5ff7d815925032d4151de0 Signed-off-by: Jeremy Compostella <jeremy.compostella@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/70300 Reviewed-by: Tarun Tuli <taruntuli@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
