scripts/dtc: Add a script to update to mainline dtc source
A very simple script that automates pulling in a newer version of DTC.
Not particularly robust, but a whole lot better than doing it by hand
every time.

# 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
