# Current options for AVR:
#     halfkay      PJRC Teensy
#     caterina     Pro Micro (Sparkfun/generic)
#     atmel-dfu    Atmel factory DFU
#     lufa-dfu     LUFA DFU
#     qmk-dfu      QMK DFU (LUFA + blinkenlight)

#     bootloadhid  HIDBootFlash compatible (ATmega32A)

# If you need to provide your own implementation, you can set inside `rules.mk`
# `BOOTLOADER = custom` -- you'll need to provide your own implementations. See

#
# BOOTLOADER_SIZE can still be defined manually, but it's recommended
# you add any possible configuration to this list
