[POWERPC] Fix build failure for tqm8540 and sbc85xx defconfigs
[linux-2.6.git] / 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.
