[PATCH] ppc: Fix ARCH=ppc build with xmon
[linux-3.10.git] / 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.
