There is an issue with current barebox.

The /dev/phy0 device not present just after boot. You need somehow to use network
to make it appeared.

Use this [ugly!] method:
  Run barebox on your board. Just after boot /dev/phy0 is absent.
  So run 'dhcp' command. In a few seconds press "ctrl-c" to interrupt it.
  Check /dev/phy0 presence.
