7# This script takes a kernel binary and optionally an initrd image
8# and/or a device-tree blob, and creates a bootable zImage for a
9# given platform.
10
11# Options:
12# -o zImage specify output file
13# -p platform specify platform (links in $platform.o)
14# -i initrd specify initrd file
15# -d devtree specify device-tree blob
16# -s tree.dts specify device-tree source file (needs dtc installed)
17# -c cache $kernel.strip.gz (use if present & newer, else make)
18# -C prefix specify command prefix for cross-building tools
19# (strip, objcopy, ld)
20# -D dir specify directory containing data files used by script
21# (default ./arch/powerpc/boot)
22# -W dir specify working directory for temporary files (default .)
