Reference discussion in avrdude

Optiboot returns Flash for EEPROM if optiboot has been compiled to not handle EEPROM. This bug has been around for a long time and it is still there now.

I'm always a bit unclear on what should happen in these cases. There doesn't seem to be a way for the bootloader to respond "That operation isn't supported" in a way that avrdude (or other app) will be able to given an understandable error message to the user.
