  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
