The phylib output points at a Microchip LAN8710A ethernet PHY
while older revisions of the A20-Olinuxino MICRO used a Realtek
RTL8201CP instead. As far as I can tell from a quick glance at
the PHY driver sources in the Linux kernel, there doesn't seem to
be a PHY-specific driver for the LAN8710A. The microchip PHY
driver seems to support only the LAN88XX series (PHY ID
0007c130), but not the LAN87XX series.
AFAICS u-boot 2016.11 (the version used by Debian) also doesn't
have a PHY-specific driver for the Microchip LAN8710A.
Some PHYs work properly with a generic PHY driver, but quite a
lot of PHY models require a chip-specific setup, so that might
well be the problem at hand. I am not particularly familiar with
the PHY driver code nor do I have knowledge about the specifics
of the LAN8710A, so unfortunately I cannot help you here much
further. I'll reassign the bug to the Debian kernel package,
perhaps one of the kernel maintainers can provide further
information.

Karsten
