# LUFA DFU Bootloader Buildsystem Makefile Module.
# -----------------------------------------------------------------------------
# DESCRIPTION:
# Provides a set of targets to re-program a device currently running a DFU
# class bootloader with a project's FLASH and EEPROM files.
# -----------------------------------------------------------------------------
# TARGETS:
#
# flip - Program FLASH into target via Atmel FLIP
# flip-ee - Program EEPROM into target via Atmel FLIP
# dfu - Program FLASH into target via dfu-programmer
# dfu-ee - Program EEPROM into target via dfu-programmer
#
# MANDATORY PARAMETERS:
#
# MCU - Microcontroller device model name
# TARGET - Application name
#
# OPTIONAL PARAMETERS:
#
# (None)
#
# PROVIDED VARIABLES:
#
# (None)
#
# PROVIDED MACROS:
#
# (None)
