Linus Torvalds1da177e2005-04-16 15:20:36 -07001# 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
David Gibsonb610b972007-05-29 15:37:12 +100014# 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.
Linus Torvalds1da177e2005-04-16 15:20:36 -070016# 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.
