Please hold off merging this patch until someone tested it, I can not do so this week. @Tom Can you confirm if this fixes the networking on your Cubox? Also note that the phy-handle property may or may not be required, I am not sure.

The i.MX6 Cubox-i and HummingBoards can have different PHYs at varying addresses. U-Boot needs to auto-detect which phy is actually present, and at which address it is responding.
Auto-detection from multiple phy nodes specified in device-tree does not currently work correct. As a work-around merge all three possible phys into one node with the special address 0xffffffff which indicates to the generic phy driver to probe all addresses. Also fixup this fake address before booting Linux, *if* booting with U-Boot's internal dtb.

Should you patch the u-boot.dtsi variant instead (arch/arm/dts/imx6qdl-sr-som-u-boot.dtsi) ?
This way the next time the DTS re-sync is done, the problem does not appear again.
