[U-Boot-Users] [PATCH] 86xx: write MAC address to mac-address and local-mac-address

[Timur Tabi]

Some device trees have a mac-address property, some have local-mac-address,
and some have both.  To support all of these device trees, ftp_cpu_setup() 
should write the MAC address to mac-address and local-mac-address, if they
exist.
