[PATCH] xilinx: Enable NVMEM framework for all platforms
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.
