> the whole series add support for I2C based FRU eeprom board identification.
> EEPROMs are referenced by nvmem alias which was suggested by Rob Herring
> (dt maintainer). Previous code was using chosen xlnx,eeprom property.
> And because no platform is setting up nvmem alias the code is doing nothing
> on all boards.
>
> If you want to try it and test it just choose board and define nvmem
> aliases and you should see similar logs like this.
