   1 # SPDX-License-Identifier: GPL-2.0
   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.
