arch/powerpc/boot/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.

  67 # The pre-boot decompressors pull in a lot of kernel headers and other source
  68 # files. This creates a bit of a dependency headache since we need to copy
  69 # these files into the build dir, fix up any includes and ensure that dependent
  70 # files are copied in the right order.
  71
  72 # these need to be seperate variables because they are copied out of different
  73 # directories in the kernel tree. Sure you COULd merge them, but it's a
  74 # cure-is-worse-than-disease situation.
