+# Makefile for making bootable images on various OpenFirmware machines.
+#
+# Paul Mackerras	January 1997
+#	XCOFF bootable images for PowerMacs
+# Geert Uytterhoeven	September 1997
+#	ELF bootable iamges for CHRP machines.
+# Tom Rini		January 2001
+# 	Cleaned up, moved into arch/ppc/boot/pmac
+# Tom Rini		July/August 2002
+#	Merged 'chrp' and 'pmac' into 'openfirmware', and cleaned up the
+#	rules.
