In order to update MAC address entry in Device Tree both mainline U-Boot
(in function fdt_fixup_ethernet) and Barebox (in function eth_of_fixup)
accept same (and the only one) format of eth aliases, which is 'ethernetX',
where X stands for interface number.
Other platforms in the mainline Linux, that comprise ethernet references in
'/aliases' node (like various flavours of imx or sunXi), follow the naming
scheme described above.
Is this explanation sufficient? Do you think I should extend the commit log?

Best regards,
Marcin Wojtas
