/** \brief Bootloader Size in *bytes*
|

*
|

* AVR Boot section size are defined by setting BOOTSZ fuse in fact. Consult with your MCU datasheet.
|

* Note that 'Word'(2 bytes) size and address are used in datasheet while TMK uses 'Byte'.
|

*
|

* Size of Bootloaders in bytes:
|

* Atmel DFU loader(ATmega32U4) 4096
