Not all AWM boards have mac address setup in preinit script. Only AWM002 EVB ones are defined. I don't believe you had good macs on same boards a week ago. I proposed a patch which moves mac address extraction from preinit to dts: http://patchwork.openwrt.org/patch/5970/ Look at that patch and you will see how to add ethernet mac to dts to other AWM boards.
