I confirm that this patch applies mostly cleanly (modulo minor Makefile issue) to v5.16 and that it works with the vendor cboot on a Xavier AGX device. I assume that it is expected that the earlycon output comes out twice (once from the earlycon driver and another time from the real driver). Tested-by: Helmut Grohne Some of the concerns from Thierry Reding remain unaddressed though. Helmut
