Hi, I didn't investigate the difference between AArch64 and AArch32. But I believe that AArch64 should be better structured. As of GIC and Generic Timer, I think you are right. I plan to start committing it in coherent chunks as soon as I can. And yes, I hope I finish it before May. Best regards, Sergey
