Allwinner A64 SoC has an EMAC which is used to provide Ethernet function on several boards. The EMAC itself doesn't have a fixed MAC address, but the sunxi mainline U-Boot have the ability to generate one based on the eFUSE SID in the chip, and add the generated MAC address to the device tree when booting. The MAC address setting step is based on the device tree's aliases, and device tree nodes prefixed "ethernet" will get the MAC address added. However, in several A64 boards' device tree, the alias is not set up, so that the U-Boot won't set the MAC address. Add the ethernet0 aliases to these boards. I hope this patchset can be queued in 4.13, otherwise 4.13 kernels won't get non-volatile MAC addresses, and will use random ones instead, which is annoying to many users.
