From: Monish Chunara <redacted> Integrate the GT24C256C EEPROM via I2C to enable access to board-specific non-volatile data. Also, define an nvmem-layout to expose structured regions within the EEPROM, allowing consumers to retrieve configuration data such as Ethernet MAC addresses via the nvmem subsystem.

I'm not super happy that this would be the only line of defense, but you probably want to add 'read-only' to the eeprom node (or not) Reviewed-by: Konrad Dybcio <redacted> Konrad
