Anyone is working/plan to add GICv3 driver?

This is part of the architectural support, and pulled in that way from Tianocore. It supports using a GICv3 in "legacy" GICv2 mode.

I expect ARM will provide a non-legacy GICv3 driver at some point, but I do not know the exact roadmap.

I started to work on a UEFI GICv3 driver last year. It is almost working but I had to switch to higher priority tasks since then. I have the plan to clean and publish this driver soon. I would say by then of April, but I do not want to commit to any date. If it is blocking you then I can send an early version of the patch.
