This machine is an open hardware router by cz.nic driven by a
Marvell Armada 385.

Hello,
the following components are working:
- WAN port
- eMMC
- UART0
- USB
Still missing is support for the switch. Wireless fails to probe, didn't
debug this up to now. SFP is untested as is UART1.
The device tree on the device doesn't specify a board compatible, I added
"turris,omnia". Do I need to "register" turris in vendor-prefixes.txt for that?
@Tomas+Martin: Is this correct at all, or should I better reference cz.nic?
Best regards
Uwe
