http://git.yoctoproject.org/cgit/cgit.cgi/meta-xilinx/commit/?h=dizzy&id=d429b1986931dac94b54acb1821d07e02cc532ce

I did some quick tests, but let me know if there are any issues.

Nathan

The macb driver does not honor the phy-handle property and so with the older binding for the phy node in the meta-xilinx device-trees it fails to see the defined phy node and instead goes and scans for a phy.
