Well, I don't think it's a good idea. Each board should have a different mac address and it's nomally stored somewhere in the boards non-volatile storage during board bringup. > I'll try to cook something up. But not via platform data, please. Or have I missed something. With the flat device tree (as used for PowerPC) the situation is different because the boot-loader can fixup the MAC address before booting Linux. Wolfgang.
