Hey, your right so far, Warhead has this driver in an old git. https://github.com/WarheadsSE/OX820-3.1-Linux
And beside from raid, cardreader, front usb3.0 and gpio, this non-fdt works so far.
The cardreader, front usb3.0 and gpio is I not the hard task.
With try to use the raid here I got:
I'm not sure if this driver is capable of fdt, so maybe it might be better to work on the "newer" sata driver and add there the second port. But after many hours of looking into the code of the sata_oxnas.c I realized my coding skills are to low :-(.
