It uses single core Cortex-A7, doesn't have SDU or local (TWD) timer. It was also stripped out of independent SPI controller and 2 GMACs. DTS for Tenda AC9 isn't completed yet. It misses e.g. switch entry (we still need some bgmac/b53 fixes) and probably some clocks. It adds support for basic features however and can be improved later.
