IIRC he's waiting on some PRs to get merged upstream in the Tianocore EDK2 repos. I think someone was working on porting the lx2160a_uefi repo but I haven't heard much about it in a while. If you're a Discord user, Jon Nettleton - one of SolidRun's engineers - and a handful of others who are playing with Honeycombs in different capacities are also collaborating here: https://discord.gg/tgHuG4Cq
