1 # Makefile for making bootable images on various OpenFirmware machines.
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.
