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