Since the beginning the upper USB port on Pine64 boards (Pine64+, SoPine baseboard, Pine64-LTS, Pinebook) was not working under U-Boot. This is due to the PHY for those pins being shared with the OTG controller, which we didn't even enable for those boards. Also the PHY code was always connecting the port pins to the OTG controller.
These two patches fix this, so the upper USB port on said boards can be used within U-Boot. This allows to use an USB keyboard alongside an USB flash drive, for instance to install operating systems using UEFI. Cheers, Andre.
