   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
