#
# @brief mk occ application
#
# This Makefile is included-ed into application Makefiles and
# encapsulates the steps necessary to create application images.
#
# The application Makefile (user) must define the following variables:
#
# APP - The name of the application
# SOURCES - The list of local source files that implement the
# application.
#
# The application Makefile (user) may optionally define the following
# variables:
#
# D - The value of $(D) is appended to DEFS defined by ssx.mk
#
# MODE - The following modes are recognized:
#
# validation - (Default) An application that requires all SSX
# services.
#
# firmware - An interrupt only configuration.
#
# The make process creates the following files:
#
# $(APP).out - The PowerPC-ELF version of the application
# $(APP).bin - A binary SRAM image of the application
# $(APP).map - The linker map of the application
