kbuild: limit dtc+cpp include path

2013-02-13T10:12:10Z

Device tree source files may now include header files. The intent is that those header files define/name constants used as part of the DT bindings. Currently this feature is open to abuse, since any kernel header file at all can be included, This could allow device tree files to become dependant on kernel headers files, and thus make them no longer OS-independent. This would also prevent separating the device tree source files from the kernel repository. Solve this by limiting the cpp include path for device tree files to separate directories.

kbuild: create a rule to run the pre-processor on *.dts files

2013-02-08T14:38:07Z

Create cmd_dtc_cpp to run the C pre-processor on *.dts file before passing them to dtc for final compilation. This allows the use of #define and #include within the .dts file.

kbuild: centralize .dts->.dtb rule

2012-11-30T16:52:19Z

All architectures that use cmd_dtc do so in almost the same way. Create a central build rule to avoid duplication. The one difference is that most current uses of dtc build $(obj)/%.dtb from $(src)/dts/%.dts rather than building the .dtb in the same directory as the .dts file. This difference will be eliminated arch-by-arch in future patches. MIPS is the exception here; it already uses the exact same rule as the new common rule, so the duplicate is removed in this patch to avoid any conflict. arch/mips changes courtesy of Ralf Baechle. Update Documentation/kbuild to remove the explicit call to cmd_dtc from the example, now that the rule exists in a centralized location.

Kbuild: centralize MKIMAGE and cmd_uimage definitions

2012-03-26T13:49:20Z

All ARCHs have the same definition of MKIMAGE. Move it to Makefile.lib to avoid duplication. All ARCHs have similar definitions of cmd_uimage. Place a sufficiently parameterized version in Makefile.lib to avoid duplication.

Kbuild: Use dtc's -d (dependency) option

2012-01-14T23:04:35Z

This hooks dtc into Kbuild's dependency system. Thus, for example, "make dtbs" will rebuild tegra-harmony.dtb if only tegra20.dtsi has changed yet tegra-harmony.dts has not. The previous lack of this feature recently caused me to have very confusing "git bisect" results. For ARM, it's obvious what to add to $(targets). I'm not familiar enough with other architectures to know what to add there. Powerpc appears to already add various .dtb files into $(targets), but the other archs may need something added to $(targets) to work.

kbuild: Fix comment in Makefile.lib

2012-01-08T20:54:43Z

KBUILD_MODNAME is not defined for files that are linked into multiple modules, and trying to change reality to match documentation would result in all sorts of trouble. E.g. options for built-in modules would be called either foo_bar.param, foo.param, or bar.param, depending on the configuration. So just change the comment. Signed-off-by: Michal Marek

kbuild: prevent make from deleting _shipped files

2011-08-31T14:35:56Z

commit 7373f4f (kbuild: add implicit rules for parser generation) created a implicit rule chain (%.c: %.c_shipped: %.y). Make considers the _shipped files to be intermediate files which causes them to be deleted if they didn't exist before make was run. Mark the _shipped files PRECIOUS to prevent make from deleting them. Signed-off-by: Peter Foley Acked-by: Arnaud Lacombe Signed-off-by: Michal Marek

kbuild: simplify the %_shipped rule

2011-06-09T18:04:39Z

This is needed to have make(1) correctly link the implicit rules which generate the _shipped file from the lexer/parser to the final file. Signed-off-by: Arnaud Lacombe
