Are you actively working on this ?

In my action list, I also wanted to enable libgfxinit in ramstage. The idea being to not waste time in issues which could be related to running it before FSP on MTL. I created https://review.coreboot.org/c/coreboot/+/72731 for this. libgfxinit does not execute a lot better in ramstage than in romstage. Some Adaptation for gen12+ is clearly necessary.

Anil will be leading this activity as I have to focus on another topic.
