There is an I2C eeprom connected on Lenovo ix4-300d, add the corresponding node. Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com> --- IIRC, the eeprom contains some register init pairs (address, data) for and is empty otherwise. I'll have to check the boot loader code again, but (again) IIRC, stock u-boot already does the sequence in code and ignores the eeprom.
