2# Makefile for making ELF bootable images for booting on CHRP
3# using Open Firmware.
4#
5# Geert Uytterhoeven	September 1997
6#
7# Based on coffboot by Paul Mackerras
8# Simplified for ppc64 by Todd Inglett
9#
10# NOTE:	this code is built for 32 bit in ELF32 format even though
11#	it packages a 64 bit kernel.  We do this to simplify the
12#	bootloader and increase compatibility with OpenFirmware.
13#
14#	To this end we need to define BOOTCC, etc, as the tools
15#	needed to build the 32 bit image.  That's normally the same
16#	compiler for the rest of the kernel, with the -m32 flag added.
17#	To make it easier to setup a cross compiler,
18#	CROSS32_COMPILE is setup as a prefix just like CROSS_COMPILE
19#	in the toplevel makefile.
