Following commit broke DW GMAC functionality on AXS10x boards:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=e34d65696d2ef13dc32f2a162556c86c461ed763
That's what happens on eth0 up:
--------------------------->8------------------------
libphy: PHY stmmac-0:ffffffff not found
eth0: Could not attach to PHY
stmmac_open: Cannot attach to PHY (error: -19)
--------------------------->8------------------------
Simplest solution is to add PHY description in board's .dts.
And so we do here.
