i.MX7D U-Boot not seeing ENET

Bringing up a new i.MX7D-based board.  U-Boot doesn't see any FEC MXC ENET interfaces.  Using LAN8710ai.

According to the board designer the ENET1 hardware and configuration closely resembles the mx7dsabresd.  I am admittedly inexperienced with this bring-up task.  What should I be looking for?

 

Attached is a capture of the boot output; board files and modified fec_mxc.c (only fecmxc_initialize_multi() modified to dump phy search results).  Performing "mii info" after interrupting boot displays "NULL device name!  No such device: <NULL>"

 

Thank you,   Joe
