Since I have one of these gathering dust on my desk, it's really cool to
see this series, thanks!
I've successfully booted that branch to a filesystem on SD card, but USB
clearly isn't quite right - the USB 2.0 hub is powered up, but only the
bottom right port will actually enumerate devices; the ethernet is
nowhere to be seen. However, if I drop into the bootloader and do a "usb
start" beforehand, it all keeps working into the kernel. As for the USB
3.0, though, the ports report over-current conditions shortly after the
XHCI probe despite having nothing plugged in :(
