Peter,
Thanks for the response and the info about upstream support. I used both the "orangepi_pc" and "nanopi_neo" profiles to get a successful boot, however when I used the "nanopi_neo" profile, neither ethernet port worked, it was only when I used the "orangepi_pc" profile that I was able to get one of the ethernet ports to work. As far as the machine model, it reports "Xunlong Orange Pi PC".
With some testing, I can confirm that everything else is working as it should: USB works, the two onboard serial ports, and the single ethernet port, just not the second ethernet or onboard wifi. I have also attached a txt file with the output from the "lshw" command, for your reference.
