Some versions (possibly forked by vendors) might set the MAC address
automatically in DT, but in my case I have the following in my boot script:
tftp 0x80800000 beagle/omap3-beagle-xm.dtb
fdt addr ${fileaddr} ${filesize}
fdt resize
fdt set /ocp@68000000/usbhshost@48064000/ehci@48064800/usb2@2/usbether@1 local-mac-address "[7a d2 a0 00 d1 f0]"
