These patches enable support for USB 2.0 on the Renesas RZ/G2L EVK, supporting both the USB Type-A port and the USB OTG port. It is possible to load and boot Linux from a USB Mass Storage device connected to either port.
There should be no change to the operation of R-Car gen3 boards, but I don't have any of them available to test to confirm this myself.
