On current master (7.3-rc2) the unpatched driver registers and immediately warns: "[PLANE:35:plane-0] pixel format with alpha exposed but blend mode not setup", which kills the boot with panic_on_warn. With v3 below, the same boot registers pl111 with no warnings at all. One note: 860e748bddcc is not in v7.2, so the splat only shows up on master/7.3 and later. v3 also removes the alpha formats from the board-specific tables in pl111_versatile.c that the sashiko review caught v2 missing.
