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