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).

Some of the concerns from Thierry Reding remain unaddressed though.
