2018-05-31scripts/dtc: Re-sync with Linux 4.17-rc4Eugeniu Rosca
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 de163ecedb8a ("scripts: dtc: Add .gitignore") * v2018.01 15b97f5c5e6d ("pylibfdt: move pylibfdt to scripts/dtc/pylibfdt and refactor makefile") Signed-off-by: Eugeniu Rosca <erosca@de.adit-jv.com> Reviewed-by: Simon Glass <sjg@chromium.org> Reviewed-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2017-11-17pylibfdt: compile pylibfdt only when dtoc/binman is necessaryMasahiro Yamada
Currently, pylibfdt is always compiled if swig is installed on your machine. It is really annoying because most of targets (excepts x86, sunxi, rockchip) do not use dtoc or binman. "checkbinman" and "checkdtoc" are wrong. It is odd that the final build stage checks if we have built necessary tools. If your platform depends on dtoc/binman, you must be able to build pylibfdt. If swig is not installed, it should fail immediately. I added PYLIBFDT, DTOC, BINMAN entries to Kconfig. They should be property select:ed by platforms that need them. Kbuild will descend into scripts/dtc/pylibfdt/ only when CONFIG_PYLIBFDT is enabled. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2017-11-17pylibfdt: move pylibfdt to scripts/dtc/pylibfdt and refactor makefileMasahiro Yamada
The pylibfdt is used by dtoc (and, indirectly by binman), but there is no reason why it must be generated in the tools/ directory. Recently, U-Boot switched over to the bundled DTC, and the directory structure under scripts/dtc/ now mirrors the upstream DTC project. So, scripts/dtc/pylibfdt is the best location. I also rewrote the Makefile in a cleaner Kbuild style. The scripts from the upstream have been moved as follows: lib/libfdt/pylibfdt/setup.py -> scripts/dtc/pylibfdt/setup.py lib/libfdt/pylibfdt/libfdt.i -> scripts/dtc/pylibfdt/libfdt.i_shipped The .i_shipped is coped to .i during building because the .i must be located in the objtree when we build it out of tree.

2017-09-23scripts/dtc: Update to upstream version v1.4.3Tom Rini
Using the update-dtc-source.sh script from Linux v4.14-rc1 import the portions of dtc that we require. We bring in update-dtc-source.sh and scripts/dtc/Makefile from Linux v4.14-rc1. Rework DTC_FLAGS handling to not require a test. Signed-off-by: Tom Rini <trini@konsulko.com>
