1 # Makefile for making ELF bootable images for booting on CHRP
4 # Geert Uytterhoeven September 1997
6 # Based on coffboot by Paul Mackerras
7 # Simplified for ppc64 by Todd Inglett
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.
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.
