After building dtc in the dtc directory, it copies the# source files and generated source file(s) into the scripts/dtc directory# in the kernel and creates a git commit updating them to the new# version.## Usage: from the top level Linux source tree, run:# $ ./scripts/dtc/update-dtc-source.sh## The script will change into the dtc tree, build and test dtc, copy the# relevant files into the kernel tree and create a git commit. The commit# message will need to be modified to reflect the version of DTC being# imported## TODO:# This script is pretty basic, but it is seldom used so a few manual tasks# aren't a big deal. If anyone is interested in making it more robust, the# the following would be nice:# * Actually fail to complete if any testcase fails.# - The dtc "make check" target needs to return a failure# * Extract the version number from the dtc repo for the commit message# * Build dtc in the kernel tree# * run 'make check" on dtc built from the kernel tree
