[U-Boot] Ethernet on Colombus (sun6i-a31-colombus)

[Quentin Schulz]

Hi,

I put U-Boot for the Colombus on an SD Card but could not make Ethernet
work.

In U-Boot v2015.10, v2016.01 and v2016.05, Ethernet port is not detected.
In U-Boot v2016.03, the Ethernet port is detected but cannot be used. I
get the following error:

=> dhcp
ethernet at 01c30000 Waiting for PHY auto negotiation to complete.........
TIMEOUT !
ethernet at 01c30000: No link.

Thank you,

Quentin
