Interesting, I was a bit surprised that this would be all we need, but indeed everything else falls into place, when none of the newer SoCs are used.

The V3s is identical regarding register layout, clocks and resets to the sun6i variants. Therefore, we can just add the MACH_SUN8I_V3S to the sun6i compatible ones. SPI boot was tested on a custom board with a Gigadevice GD25Q64 8MiB SPI flash.
