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.
