#               LUFA HID Bootloader Buildsystem Makefile Module.
# -----------------------------------------------------------------------------
# DESCRIPTION:
#   Provides a set of targets to re-program a device currently running a HID
#   class bootloader with a project's FLASH files.
# -----------------------------------------------------------------------------
# TARGETS:
#
#    hid                       - Program FLASH into target via
#                                hid_bootloader_cli
#    hid-ee                    - Program EEPROM into target via a temporary
#                                AVR application and hid_bootloader_cli
#    teensy                    - Program FLASH into target via
#                                teensy_loader_cli
#    teensy-ee                 - Program EEPROM into target via a temporary
#                                AVR application and teensy_loader_cli
#
# MANDATORY PARAMETERS:
#
#    MCU                       - Microcontroller device model name
#    TARGET                    - Application name
#
# OPTIONAL PARAMETERS:
#
#    (None)
#
# PROVIDED VARIABLES:
#
#    (None)
#
# PROVIDED MACROS:
#
#    (None)
