+# Makefile for making ELF bootable images for booting on CHRP
+# using Open Firmware.
+#
+# Geert Uytterhoeven	September 1997
+#
+# Based on coffboot by Paul Mackerras
+# Simplified for ppc64 by Todd Inglett
+#
+# NOTE:	this code is built for 32 bit in ELF32 format even though
+#	it packages a 64 bit kernel.  We do this to simplify the
+#	bootloader and increase compatibility with OpenFirmware.
+#
+#	To this end we need to define BOOTCC, etc, as the tools
+#	needed to build the 32 bit image.  These are normally HOSTCC,
+#	but may be a third compiler if, for example, you are cross
+#	compiling from an intel box.  Once the 64bit ppc gcc is
+#	stable it will probably simply be a compiler switch to
+#	compile for 32bit mode.
+#	To make it easier to setup a cross compiler,
+#	CROSS32_COMPILE is setup as a prefix just like CROSS_COMPILE
+#	in the toplevel makefile.
