Ping? I just wanted to follow up on this discussion as this small series is crucial for booting mainline on the Dragonboard 845c devboard. It would be really valuable to be able to get some solution upstream so we can test mainline w/o adding additional patches. The rest of the db845c series has been moving forward smoothly, but this set seems to be very stuck with no visible progress since Dec. Are there any pointers for what folks would prefer to see? thanks -john
