* kbuild: Don't reset timestamps in include/generated if not neededMichal Marek2015-03-281-9/+9
| | | | | | | | | | | | | Use filechk to generate asm-offsets.h and generic-asm-offsets.h. Based on a patch by Valdis Kletnieks.

* kbuild: merge generic-asm-offsets.h and asm-offsets.h rulesMasahiro Yamada2015-03-281-40/+22
| | | | | | | | | | | | | | | | The rules "cmd_generic-offsets" and "cmd_offsets" are almost the same. (The difference is only the include guards.) They can be merged. This commit is mostly inspired by the following commit of Linux. commit 39664e2f3cdef98f42437e903159a6044a1d99d6 Author: Masahiro Yamada <yamada.m@jp.panasonic.com> Date: Mon Jan 5 15:57:15 2015 +0900 kbuild: merge bounds.h and asm-offsets.h rules Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* clang: workaround for generated constantsJeroen Hofstee2014-09-091-1/+2
| | | | | | | | | | KBuild abuses the asm statement to write to a file and clang chokes about these invalid asm statements. Hack it even more by fooling this is actual valid asm code. cc: Masahiro Yamada <yamada.m@jp.panasonic.com> cc: Tom Rini <trini@ti.com> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>
* kbuild: move asm-offsets.c from SoC directory to arch/$(ARCH)/libMasahiro Yamada2014-03-281-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | U-Boot has supported two kinds of asm-offsets.h. One is generic for all architectures and its source is located at ./lib/asm-offsets.c. The other is SoC specific and its source is under SoC directory. The problem here is that only boards with SoC directory can use the asm-offsets infrastructure. Putting asm-offsets.c right under CPU directory does not work. Now a new demand is coming. PowerPC folks want to use asm-offsets. But no PowerPC boards have SoC directory. It seems inconsistent that some boards add asm-offsets.c to SoC directoreis and some to CPU directories. It looks more reasonable to put asm-offsets.c under arch/$(ARCH)/lib. This commit merges asm-offsets.c under SoC directories into arch/$(ARCH)/lib/asm-offsets.c. By the way, I doubt the necessity of some entries in asm-offsets.c. I am leaving refactoring to the board maintainers. Please check "TODO" in the comment blocks in arch/{arm,nds32}/lib/asm-offsets.c.

* kbuild: move asm-offsets.h rules to ./KbuildMasahiro Yamada2014-02-251-0/+87
Generate include/generated/generic-asm-offsets.h and include/generated/asm-offsets.h in ./Kbuild. This commit also changes the include guard. Before this commit, __ASM_OFFSETS_H__ was used for both of them. So we could not include generic-asm-offsets.h and asm-offsets.h at the same time. This commit renames the include guard of the former to __GENERIC_ASM_OFFSETS_H__. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
