# Simple script to update the version of DTC carried by the Linux kernel |
|
# |
|
# This script assumes that the dtc and the linux git trees are in the |
|
# same directory. 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 |
