David Gibson 430b01e8f5 [POWERPC] Kill flatdevtree.c 
Now that earlier patches have switched the bootwrapper to using libfdt
for device tree manipulation, this patch removes the now unused
flatdevtree.c and related files.

# 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.
