# -----------------------------------------------------------------------------
#               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)
#
