# 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.  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.
