 # 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 may be 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.  That's normally the same
 #	compiler for the rest of the kernel, with the -m32 flag added.
 #	To make it easier to setup a cross compiler,
 #	CROSS32_COMPILE is setup as a prefix just like CROSS_COMPILE
 #	in the toplevel makefile.

 # files are copied in the right order.

 # these need to be seperate variables because they are copied out of different
 # directories in the kernel tree. Sure you COULd merge them, but it's a

	# using Open Firmware.
	#
	# Geert Uytterhoeven September 1997
	#
	# Based on coffboot by Paul Mackerras
	# Simplified for ppc64 by Todd Inglett
	#
	# NOTE: this code may be 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. That's normally the same
	# compiler for the rest of the kernel, with the -m32 flag added.
	# To make it easier to setup a cross compiler,
	# CROSS32_COMPILE is setup as a prefix just like CROSS_COMPILE
	# in the toplevel makefile.
