#!/bin/sh # 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 set -ev setglobal DTC_UPSTREAM_PATH = "$[pwd]/../dtc" setglobal DTC_LINUX_PATH = "$[pwd]/scripts/dtc" setglobal DTC_SOURCE = '"checks.c data.c dtc.c dtc.h flattree.c fstree.c livetree.c srcpos.c \ srcpos.h treesource.c util.c util.h version_gen.h Makefile.dtc \ dtc-lexer.l dtc-parser.y'" setglobal DTC_GENERATED = '"dtc-lexer.lex.c dtc-parser.tab.c dtc-parser.tab.h'" setglobal LIBFDT_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'" # Build DTC cd $DTC_UPSTREAM_PATH make clean make check # Copy the files into the Linux tree cd $DTC_LINUX_PATH for f in [$DTC_SOURCE] { cp $(DTC_UPSTREAM_PATH)/$(f) $(f) git add $(f) } for f in [$DTC_GENERATED] { cp $(DTC_UPSTREAM_PATH)/$f $(f)_shipped git add $(f)_shipped } for f in [$LIBFDT_SOURCE] { cp $(DTC_UPSTREAM_PATH)/libfdt/$(f) libfdt/$(f) git add libfdt/$(f) } sed -i -- 's/#include /#include "libfdt_env.h"/g' ./libfdt/libfdt.h sed -i -- 's/#include /#include "fdt.h"/g' ./libfdt/libfdt.h git add ./libfdt/libfdt.h git commit -e -v -m "scripts/dtc: Update to upstream version [CHANGEME]"
