makefile

MIPS下的boottloader yamon 的源代码

#########################################################################
#
# Makefile used for building YAMON.
# 
# After adapting the "Environment specifics" section of this makefile
# (see below), the makefile may be used in the specific build 
# environment.
#
# Note, that this makefile uses forward slashes '/' for directory
# references.
#
# The default target (all) builds YAMON in two formats :
#
# yamon-<rev>.fl :  The YAMON image used for loading YAMON to a
#		    target board using the parallel port.
#
# yamon-<rev>.bin : The YAMON image (binary) used for programming
#		    an (E)PROM.
#
# Other targets are : 
#
# install :	    Creates the necessary directories and
#		    builds the tools needed for the main build.
# clean :   	    Deletes all files generated by makefile.
# depend :  	    Builds dependency files.
# release : 	    First deletes all files generated by makefile (make clean).
#  		    Then builds YAMON images (make all).
#		    Then generates disassembly files.
