I boot openwrt from u-boot on my ar933x board, and the ethernet driver
can't find chip build-in PHY, but it work well if boot from original 
manufacturer's
u-boot 1.14.

[    1.854519] libphy: ag71xx_mdio: probed
[    2.646539] ag71xx-mdio.1: unknown phy id 'ffff:ffff'
[    3.235778] ag71xx ag71xx.0: no PHY found with phy_mask=00000010

Do you test this situation on your ar934x platform?
