| 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 .) |
