Allwinner A64 SoC has an EMAC which is used to provide Ethernet

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.
Icenowy Zheng (3):
arm64: allwinner: a64: add ethernet0 alias for BPi M64 EMAC node
arm64: allwinner: a64: add ethernet0 alias for Pine64 EMAC node
arm64: allwinner: a64: add ethernet0 alias for SoPine EMAC node
Applied all three, thanks!
Sorry, but could you queue them to 4.13?
Otherwise 4.13 kernel release will have annoying random MAC problem,
which heavily affects headless usages.
