USB is an ordinary VIA chip attached by pci-e. But the pci-e controller is proprietary and there is little documentation. I have been working on a driver for some time, with limited success—I can see the USB controller and enumerate the ports on it, but it doesn’t start properly. I know some other folks have been looking at directly accessing USB without initializing the pci-e controller. openBSD 6.7 has pci-e for rpi4. It uses TianoCore instead of u-boot. I believe TianoCore does the hard part of the pci-e initialization like configuring the inbound system memory view. Another mailing list contributor is working on wifi.
