I have some trouble to get it working with an eeprom backend. Just to be sure if the barebox side is ok: of_dump /state state { magic = <0x7074000a>; compatible = "barebox,state"; backend-type = "raw"; backend = "/soc/aips-bus@02100000/i2c@021a0000/eeprom@50"; linux,phandle = <0x2f>; phandle = <0x2f>; The documentation shows also "partname:" in the backend property, but for eeprom this is not valid.
