arch/powerpc/boot/Makefile - kernel/msm-4.9 - Gitiles

 # Makefile for making ELF bootable images for booting on CHRP
 # using Open Firmware.
 #
 # Geert Uytterhoeven	September 1997
 #
 # Based on coffboot by Paul Mackerras
 # Simplified for ppc64 by Todd Inglett
 #
 # NOTE:	this code is built for 32 bit in ELF32 format even though
 #	it packages a 64 bit kernel.  We do this to simplify the
 #	bootloader and increase compatibility with OpenFirmware.
 #
 #	To this end we need to define BOOTCC, etc, as the tools
 #	needed to build the 32 bit image.  That's normally the same
 #	compiler for the rest of the kernel, with the -m32 flag added.
 #	To make it easier to setup a cross compiler,
 #	CROSS32_COMPILE is setup as a prefix just like CROSS_COMPILE
 #	in the toplevel makefile.
