scripts/dtc: import update-dtc-source.sh from kernel v4.0-rc1
The original script was written by Grant Likely <grant.likely@linaro.org>. The version for barebox also imports some libfdt sources, so that we are able to compile the fdtget host tool. Also remove the unused non-kconfig makefiles. Signed-off-by: Jan Luebbe <jlu@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

# 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 files 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
