dt-bindings: Pass binding directory to validation tools

2019-05-22T14:01:01Z

In order to have $ref's to schema files within the kernel, we need to pass the base path of bindings to the schema validation tools. Cc: Masahiro Yamada Cc: Michal Marek Cc: devicetree@vger.kernel.org Cc: linux-kbuild@vger.kernel.org Signed-off-by: Rob Herring

kbuild: remove 'addtree' and 'flags' magic for header search paths

2019-05-18T02:49:57Z

The 'addtree' and 'flags' in scripts/Kbuild.include are so compilecated and ugly. As I mentioned in [1], Kbuild should stop automatic prefixing of header search path options. I fixed up (almost) all Makefiles in the kernel. Now 'addtree' and 'flags' have been removed. Kbuild still caters to add $(srctree)/$(src) and $(objtree)/$(obj) to the header search path for O= building, but never touches extra compiler options from ccflags-y etc. [1]: https://patchwork.kernel.org/patch/9632347/ Signed-off-by: Masahiro Yamada

kbuild: use $(srctree) instead of KBUILD_SRC to check out-of-tree build

2019-04-02T14:28:04Z

KBUILD_SRC was conventionally used for some different purposes: [1] To remember the source tree path [2] As a flag to check if sub-make is already done [3] As a flag to check if Kbuild runs out of tree For [1], we do not need to remember it because the top Makefile can compute it by $(realpath $(dir $(lastword $(MAKEFILE_LIST)))) [2] has been replaced with self-commenting 'sub_make_done'. For [3], we can distinguish in-tree/out-of-tree by comparing $(srctree) and '.' This commit converts [3] to prepare for the KBUILD_SRC removal. Signed-off-by: Masahiro Yamada

kbuild: move archive command to scripts/Makefile.lib

2019-03-13T17:39:10Z

scripts/Makefile.build and arch/s390/boot/Makefile use the same command (thin archiving with symbol table creation). Avoid the code duplication, and move it to scripts/Makefile.lib. Signed-off-by: Masahiro Yamada

kbuild: remove unnecessary in-subshell execution

2019-01-28T00:11:17Z

The commands surrounded by ( ) are executed in a subshell, but in most cases, we do not need to spawn an extra subshell. Signed-off-by: Masahiro Yamada

kbuild: add real-prereqs shorthand for $(filter-out FORCE,$^)

2019-01-28T00:11:17Z

In Kbuild, if_changed and friends must have FORCE as a prerequisite. Hence, $(filter-out FORCE,$^) or $(filter-out $(PHONY),$^) is a common idiom to get the names of all the prerequisites except phony targets. Add real-prereqs as a shorthand. Note: We cannot replace $(filter %.o,$^) in cmd_link_multi-m because $^ may include auto-generated dependencies from the .*.cmd file when a single object module is changed into a multi object module. Refer to commit 69ea912fda74 ("kbuild: remove unneeded link_multi_deps"). I added some comment to avoid accidental breakage. Signed-off-by: Masahiro Yamada Acked-by: Rob Herring

kbuild: simplify rules of data compression with size appending

2019-01-28T00:11:17Z

All the callers of size_append pass $(filter-out FORCE,$^). Move $(filter-out FORCE,$^) to the definition of size_append. This makes the callers cleaner because $(call ...) is unneeded for a macro with no argument. Signed-off-by: Masahiro Yamada

kbuild: skip 'addtree' and 'flags' magic for external module build

2019-01-28T00:11:17Z

When building an external module, $(obj) is the absolute path to it. The header search paths from ccflags-y etc. should not be tweaked. Signed-off-by: Masahiro Yamada

kbuild: change filechk to surround the given command with { }

2019-01-06T00:46:51Z

filechk_* rules often consist of multiple 'echo' lines. They must be surrounded with { } or ( ) to work correctly. Otherwise, only the string from the last 'echo' would be written into the target. Let's take care of that in the 'filechk' in scripts/Kbuild.include to clean up filechk_* rules. Signed-off-by: Masahiro Yamada

kbuild: remove redundant target cleaning on failure

2019-01-06T00:46:51Z

Since commit 9c2af1c7377a ("kbuild: add .DELETE_ON_ERROR special target"), the target file is automatically deleted on failure. The boilerplate code ... || { rm -f $@; false; } is unneeded. Signed-off-by: Masahiro Yamada
