I started to write the boards files for the ARCH_MIX board. For now, I used the following names for the pins:
Maybe you could use the names in the form Jn_XX, or you could use just Axx and Bxx and mention somewhere (README.md) A=J3, B=J4.
J5 is dedicated to LCD and using it is very hard if you don't have some kind of expansion board with 50-pin FPC konnector, maybe it is better to not add this connector at all.
External PHY can be easily added. KSZ8081 is cheap and available and designing the PCB for it should not be hard. I have some plans to do it myself, maybe next month.
I'm not aware of any existing board.
Regarding Ethernet on SomLabs board, I didn't received any answer yet, but examining the board I'm quite sure there is no connection of KSZ8081 RST & INT to the module, they are probably using the polling mode for communication (?!).
After some debugging I've found that the initialization fails at early stage, while reading the PHY ID, which should succeed even without those pins connected. There is probably some other issue to...
