MegaCore v2.2.0
Changelog:
- Add support for a bunch of new targets, including subvariants like A, P, and PA:
- ATmega165, ATmega325, ATmega645
- ATmega169/329/649
- ATmega3250/6450
- ATmega3290/6490
- Add support for the original Arduino MEGA 2560 bootloader.
- It's now possible to upload to a "stock" Arduino MEGA without having to re-flash the bootloader.
- You can also burn the "stock bootloader" as well
- Note that the "stock bootloader" has been slightly updated, and now supports EEPROM reads through Avrdude, something the original 2560 bootloader doesn't do.
- Fix slightly incorrect lfuse setting for AT90CAN32 and AT90CAN64
