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

Compared to the (implict) v1, the following was changed:
- disable rtc
- change compatible to cznic,turris-omnia
The following components are working:
- WAN port
- eMMC
- UART0
- USB
- mSATA
Wireless fails to probe, didn't debug this up to now.
I already see the DSA devices (with an additional change not included here),
but sending and receiving doesn't work yet.
SFP is missing as I cannot test it. UART1 is untested, but I'd be
surprised if it didn't work.
IMHO it makes sense to add the current state and fix the remaining stuff
incrementally.
Best regards
Uwe
