+# 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. These are normally HOSTCC,
+# but may be a third compiler if, for example, you are cross
+# compiling from an intel box. Once the 64bit ppc gcc is
+# stable it will probably simply be a compiler switch to
+# compile for 32bit mode.
+# To make it easier to setup a cross compiler,
+# CROSS32_COMPILE is setup as a prefix just like CROSS_COMPILE
+# in the toplevel makefile.
