ATmega128RFA1/ATmega256RFR2 do not have a unique CPU ID. Use the RC oscillator callibration byte as an impromptu CPU ID and rely on bootlader constants present on all ATmega families for the remaining bytes. This way we can provide a faux CPU ID on all ATmega MCUs and typical hobbyists with no access to JTAG adapters or high voltage programmer capable of writing the user signature have a good chance that the CPU IDs of their device do not collide.
