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 may be 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.

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.
