   9 U-Boot uses the ethernet0 alias to locate the right node to fill in
  10 the MAC address of the first ethernet interface. This patch adds the
  11 alias on all the sunxi SoCs with EMAC. In this way, people using
  12 ethernet in U-Boot (eg, for tftp) can keep a consistent address on both
  13 U-Boot and Linux with no additional effort.
