3 | # Simple script to update the version of DTC carried by the Linux kernel |
| 4 | # | |
| 5 | # This script assumes that the dtc and the linux git trees are in the | |
| 6 | # same directory. After building dtc in the dtc directory, it copies the | |
| 82bca362 | 7 | # source files and generated source file(s) into the scripts/dtc directory |
| c0e032e0 TR |
8 | # in the kernel and creates a git commit updating them to the new |
| 9 | # version. | |
| 10 | # | |
| 11 | # Usage: from the top level Linux source tree, run: | |
| 12 | # $ ./scripts/dtc/update-dtc-source.sh | |
| 13 | # | |
| 14 | # The script will change into the dtc tree, build and test dtc, copy the | |
| 15 | # relevant files into the kernel tree and create a git commit. The commit | |
| 16 | # message will need to be modified to reflect the version of DTC being | |
| 17 | # imported | |
| 18 | # | |
| 19 | # TODO: | |
| 20 | # This script is pretty basic, but it is seldom used so a few manual tasks | |
| 21 | # aren't a big deal. If anyone is interested in making it more robust, the | |
| 22 | # the following would be nice: | |
| 23 | # * Actually fail to complete if any testcase fails. | |
| 24 | # - The dtc "make check" target needs to return a failure | |
| 25 | # * Extract the version number from the dtc repo for the commit message | |
| 26 | # * Build dtc in the kernel tree | |
| 27 | # * run 'make check" on dtc built from the kernel tree | |
