Please find the attached patches that should add GICv3 support to UEFI. This patchset has been validated on SVN rev15402 (27th March 2014). The testing and review have been limited (reason why these patches have not been pushed to EDK2 repository). I do not have any ETA.
The GicDxe support GICv2 and GICv3 without requiring to be rebuilt. Feedbacks and comments are welcome.

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.

I am using git://git.linaro.org/uefi/linaro-edk2.git and i see the comments saying /* Initialize GICv3 to expose it as a GICv2 as UEFI does not

GICv3 yet */
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.
