+
+	* aclocal.m4 (SIM_AC_OPTION_HARDWARE): Add second argument,
+ 	appends extra devices.
+	(SIM_AC_OPTION_HARDWARE): Substute sim_hw, a non-duplicate list of
+ 	the device names.
+	
+	* Make-common.in (hw-config.h): New target, create hw-config.h
+ 	file.
+	(SIM_HW): Definition from @sim_hw@.
+	(hw-base.o): Depend on hw-config.h
