/arch/ppc/boot/openfirmware/Makefile

  1# Makefile for making bootable images on various OpenFirmware machines.
  2#
  3# Paul Mackerras	January 1997
  4#	XCOFF bootable images for PowerMacs
  5# Geert Uytterhoeven	September 1997
  6#	ELF bootable iamges for CHRP machines.
  7# Tom Rini		January 2001
  8# 	Cleaned up, moved into arch/ppc/boot/pmac
  9# Tom Rini		July/August 2002
 10#	Merged 'chrp' and 'pmac' into 'openfirmware', and cleaned up the
 11#	rules.
