[PATCH 0/4] Add support for I2C Legacy/FRU decoding

Hi,

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.
