0002 # Makefile for making ELF bootable images for booting on CHRP
0003 # using Open Firmware.
0004 #
0005 # Geert Uytterhoeven    September 1997
0006 #
0007 # Based on coffboot by Paul Mackerras
0008 # Simplified for ppc64 by Todd Inglett
0009 #
0010 # NOTE: this code may be built for 32 bit in ELF32 format even though
0011 #       it packages a 64 bit kernel.  We do this to simplify the
0012 #       bootloader and increase compatibility with OpenFirmware.
0013 #
0014 #       To this end we need to define BOOTCC, etc, as the tools
0015 #       needed to build the 32 bit image.  That's normally the same
0016 #       compiler for the rest of the kernel, with the -m32 flag added.
0017 #       To make it easier to setup a cross compiler,
0018 #       CROSS32_COMPILE is setup as a prefix just like CROSS_COMPILE
0019 #       in the toplevel makefile.
