At the moment, this is only used to fix-up the MAC address' OUI part
in mxs_machine_init. So my proposal would be to use
compatible = "i2se,duckbill-2", "fsl,imx28";
for the Duckbill 2 board and something like
compatible = "i2se,duckbill-2-485", "i2se,duckbill-2", "fsl,imx28";
for the rest. This way we need to add only one additional check in mxs_machine_init check.

Would this be a way to go?

Best regards,
Michael
