I suppose I can review the firmware parts if you would like me to, for 
vc4 I am pretty much clueless, and despite efforts from Emma to get the 
vc4 driver to be usable on platforms other than Pi, that never happened 
unfortunately. It would be better to keep the firmware and vc4 drivers 
decoupled, just so "wrong" assumptions are not made, but for all 
practical purposes this is the only combination that exists.
