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 .) | |
f1e510bb OH |
23 | # -z use gzip (legacy) |
24 | # -Z zsuffix compression to use (gz, xz or none) | |
