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 27 28set -ev 29 30DTC_UPSTREAM_PATH=`pwd`/../dtc 31DTC_LINUX_PATH=`pwd`/scripts/dtc 32 33DTC_SOURCE="checks.c data.c dtc.c dtc.h flattree.c fstree.c livetree.c srcpos.c \ 34 srcpos.h treesource.c util.c util.h version_gen.h Makefile.dtc \ 35 dtc-lexer.l dtc-parser.y" 36DTC_GENERATED="dtc-lexer.lex.c dtc-parser.tab.c dtc-parser.tab.h" 37LIBFDT_SOURCE="Makefile.libfdt fdt.c fdt.h fdt_empty_tree.c fdt_ro.c fdt_rw.c fdt_strerror.c fdt_sw.c fdt_wip.c libfdt.h libfdt_env.h libfdt_internal.h" 38 39# Build DTC 40cd $DTC_UPSTREAM_PATH 41make clean 42make check 43 44# Copy the files into the Linux tree 45cd $DTC_LINUX_PATH 46for f in $DTC_SOURCE; do 47 cp ${DTC_UPSTREAM_PATH}/${f} ${f} 48 git add ${f} 49done 50for f in $DTC_GENERATED; do 51 cp ${DTC_UPSTREAM_PATH}/$f ${f}_shipped 52 git add ${f}_shipped 53done 54for f in $LIBFDT_SOURCE; do 55 cp ${DTC_UPSTREAM_PATH}/libfdt/${f} libfdt/${f} 56 git add libfdt/${f} 57done 58 59sed -i -- 's/#include <libfdt_env.h>/#include "libfdt_env.h"/g' ./libfdt/libfdt.h 60sed -i -- 's/#include <fdt.h>/#include "fdt.h"/g' ./libfdt/libfdt.h 61git add ./libfdt/libfdt.h 62 63git commit -e -v -m "scripts/dtc: Update to upstream version [CHANGEME]" 64
