xref: /linux/arch/powerpc/boot/Makefile (revision 74ce1896c6c65b2f8cccbf59162d542988835835)
1# Makefile for making ELF bootable images for booting on CHRP
2# using Open Firmware.
3#
4# Geert Uytterhoeven	September 1997
5#
6# Based on coffboot by Paul Mackerras
7# Simplified for ppc64 by Todd Inglett
8#
9# NOTE:	this code is built for 32 bit in ELF32 format even though
10#	it packages a 64 bit kernel.  We do this to simplify the
11#	bootloader and increase compatibility with OpenFirmware.
12#
13#	To this end we need to define BOOTCC, etc, as the tools
14#	needed to build the 32 bit image.  That's normally the same
15#	compiler for the rest of the kernel, with the -m32 flag added.
16#	To make it easier to setup a cross compiler,
17#	CROSS32_COMPILE is setup as a prefix just like CROSS_COMPILE
18#	in the toplevel makefile.
