Versal NET platform is based on Versal chip which is reusing a lot of IPs. For more information about new IPs please take a look at DT which describe currently supported devices. The patch is adding architecture and board support with soc detection algorithm. Generic setting should be very similar to Versal but it will likely diverge in longer run.
