Todo List

## NAME

todo - Todo List

- **Module avr\_boot**

  From email with Marek: On smaller devices (all except ATmega64/128), \_\_SPM\_REG is in the I/O space, accessible with the shorter 'in' and 'out' instructions - since the boot loader has a limited size, this could be an important optimization.
