Boards which have for example MAC address in eeprom but not in Xilinx
format (legacy or FRU) could reference it via nvmem cells.
For example:

&gem0 {
        nvmem-cells = <&mac>;
        nvmem-cell-names = "mac-address";
};

&eeprom {
        #address-cells = <1>;
        #size-cells = <1>;
        mac: mac-address@f0 {
                reg = <0xf0 6>;
        };
};

For getting it work above DT changes are required but also CONFIG_NVMEM
should be enabled. That's why enable it by default in generic defconfigs
to be able to use it directly by changing DT only.
