I see two problems here.
One is that none of that device family is supported so far
(ATmega2560/2561, ATmega1280/1281, ATmega644), so the peripheral
simulation must be done. Those peripherals differ a lot from their
predecessor family (ATmega128, ATmega64).
However, as the ATmega1284 family is supported, it can probably be
used as a base for porting. I think its peripherals are very similar
to the ATmega2560 & co ones.
The second thing is that a 24-bit PC CPU core must be done. I don't
think anything to that respect has already been done.
