# This script takes a kernel binary and optionally an initrd image

# Options:
# -o zImage	specify output file
# -p platform	specify platform (links in $platform.o)
# -i initrd	specify initrd file
# -d devtree	specify device-tree blob
# -s tree.dts	specify device-tree source file (needs dtc installed)
# -c		cache $kernel.strip.gz (use if present & newer, else make)
# -C prefix	specify command prefix for cross-building tools
#		(strip, objcopy, ld)
# -D dir	specify directory containing data files used by script
#		(default ./arch/powerpc/boot)
# -W dir	specify working directory for temporary files (default .)
