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 | |
e039139b | 7 | # source files and generated source file(s) into the scripts/dtc directory |
c8a3e6a8 GL |
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 | |
