# Makefile for PMON2000 on SBS CK2 cPCI SBC board
#
# This makefile is constructed from a machine description:
#	pmoncfg <target>
# Most changes should be made in the machine description
#	Targets/<target>/conf/<target>
# after which you should do
#	pmoncfg <target>
# Machine generic makefile changes should be made in
#	Targets/<target>/conf/Makefile.<target>
# after which config should be rerun for all machines of that type.
#
# N.B.: NO DEPENDENCIES ON FOLLOWING FLAGS ARE VISIBLE TO MAKEFILE
#	IF YOU CHANGE THE DEFINITION OF ANY OF THESE RECOMPILE EVERYTHING
