Why would you do that at all?  U-Boot will run fdt_fixup_ethernet()
for all (at least AFAICT) supported architectures, which will replace 
"mac-address" and "local-mac-address" for all "ethernet?" interfaces
in the device tree for which a corresponding "ethadd" / "eth?addr"
environment variable is set.

No additional actions are needed.

Best regards,

Wolfgang Denk
