To achieve a DTC state (more or less) equivalent to Linux 4.17-rc4,
backport the DTC-specific part from below Linux commits:
b23d1a241f4eb4 ("kbuild: add %.lex.c and %.tab.[ch] to 'targets' automatically")
9a8dfb394c0467 ("kbuild: clean up *.lex.c and *.tab.[ch] patterns from top-level Makefile")
59889300274569 (".gitignore: move *.lex.c *.tab.[ch] patterns to the top-level .gitignore")
e039139be8c251 ("scripts/dtc: generate lexer and parser during build instead of shipping")
b24413180f5600 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license")
With this commit, the diff between Linux and U-boot common DTC files is:
$ git diff --stat --diff-filter=M v4.17-rc4 <this-commit> -- scripts/dtc
scripts/dtc/.gitignore | 2 +-
scripts/dtc/Makefile | 3 +++
The delta is coming from U-boot commits:
* v2017.11 de163ecedb ("scripts: dtc: Add .gitignore")
* v2018.01 15b97f5c5e ("pylibfdt: move pylibfdt to scripts/dtc/pylibfdt and refactor makefile")

# 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
