BCM53573 seems to be low priced alternative for standard Northstar
chipsets. 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.
