* Makefile: use two double-quotations as a pairMasahiro Yamada2013-12-13-1/+1
| | | | | | | | | | | | Some editors such as Emacs can highlight source files. But their parser algorithm is not perfect. If you use one double-quotation alone, some editor cannot handle it nicely and mark source lines as a string by mistake. It is preferable to use two double-quotations as a pair.

* dts/Makefile: pass -undef -D__DTS__ to cppStephen Warren2013-08-02-1/+1
| | | | | | | | | | | | This brings U-Boot's cpp invocation into line with the way the Linux kernel invokes cpp on device trees. Consistency will be useful to ensure *.dts is portable between the two. -undef also has the added advantage of not defining "linux", so DT property names such as "linux,keymap" don't get mangled.

* dts/Makefile: don't use cpp -PStephen Warren2013-08-02-1/+1
| | | | | | | | | Recent dtc supports #line directives in the input source code, and even uses them to generate useful line numbers in any messages it emits. Stop passing -P to cpp, since there's no need any more. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Simon Glass <sjg@chromium.org>

* dts/Makefile: unify cpp/dtc include pathsStephen Warren2013-08-02-2/+9
| | | | | | | | | | | | | | | | *.dts may use #include (via cpp) or /include/ (via dtc; assuming a newer dtc). The choice is up to the creator of the DT. Create a common variable DTC_INCDIRS that lists the paths searched by include statements, and update cpp and dtc invocation to use them. For cpp, also specify -nostdinc to ensure the same set of paths is available to both type of include statement. For dtc, create a new DTC_FLAGS variable to hold all the flags passed to dtc.

* dts/Makefile: simplify dtc invocationStephen Warren2013-08-02-7/+2
| | | | | | | | | | | | | | | | | | | | | | | The invocation of dtc is significantly more complex that it could be, in order to work around an issue on old versions of dtc, which print a message to stdout every time they run. Remove this workaround, on the assumption that people have or will upgrade to a newer version of dtc. This simplifies the build rule significantly. Related, split the invocation of cpp and dtc into separate commands rather than a pipeline, so that if either fail, it is detected. This has the nice benefit of saving off the result of the pre-processing step, allowing it to be easily inspected. Assuming a new enough dtc (which an earlier patch enforces), dtc will parse #line directives in its input file, and generate correct file and line numbers in error messages, even though cpp is unconditionally applied to its input file.

* Tegra: fdt: Change /include/ to #include for C preprocessorTom Warren2013-03-14-1/+2
| | | | | | | | | dts Makefile has the arch & board include paths added to DTS_CPPFLAGS. This allows the use of '#include "xyz"' in the dts/dtsi file which helps the C preprocessor find common dtsi include files.

* fdt: fix dts preprocessor optionsAllen Martin2013-02-07-1/+1
| | | | | | | | | | Using "-ansi" preprocessor option will cause dts lines that begin with '#' to choke the preprocessor. Change to "-x assembler-with-cpp" instead which is what the kernel uses to preprocess dts files.

* dts/Makefile: Turn off some predefined macrosHorst Kronstorfer2012-08-10-1/+2
| | | | | | | | | | | Add '-ansi' to DTS_CPPFLAGS to avoid unwanted expansion of dts content that matches some predefined macros. Example: A number of PowerPC related *.dts files in the kernel define a property named 'linux,network-index' which (w/o '-ansi') is expanded to '1,network-index' by the preprocessor because of '#define linux 1.'

| * fdt: Add board specific dts inclusionStephan Linz2012-07-10-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some architectures, for example Microblaze, doesn't need a splitted device tree because every Microblaze hw design is different. The individuell Microblaze device tree will be auto generated by FPGA design tools and could be used directly with dtc. The auto generated dts for Microblaze can not processed by CPP. Unfortunately that is the default procedure in U-Boot to merge a splitted device tree (substitution of ARCH_CPU_DTS). Microblaze will never use the ARCH_CPU_DTS substitution and we introduce the new board specific substitution variable BOARD_DTS that points into vendor/board/dts subdir with the file name of CONFIG_DEFAULT_DEVICE_TREE. The common dts file in vendor/dts subdir (defined by CONFIG_DEFAULT_DEVICE_TREE) contain a single include line that can processed by CPP: /include/ BOARD_DTS Signed-off-by: Stephan Linz <linz@li-pro.net> Tested-by: Michal Simek <monstr@monstr.eu> Acked-by: Simon Glass <sjg@chromium.org>
* | fdt: send all dtc output to stderrStephen Warren2012-07-09-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | Commit 896bbb5 "fdt: avoid bad MAKEALL status" added logic to capture the result code from dtc by echoing $? to stdout and capturing it using $(). However, dtc emits some diagnostics to stderr and some to stdout. The diagnostics send to stdout ended up getting captured via $() rather than being echo'd to the user. This caused those diagnostics to be passed to the exit command, which would then fail with the following cryptic error message: /bin/sh: line 1: exit: too many arguments Solve this by redirecting all dtc output to stderr so that $() does not capture it. This allows the user to see the actual error message from dtc.

* fdt: avoid bad MAKEALL statusWolfgang Denk2012-04-21-3/+7
| | | | | | | | | | | | | | | | Current versions of dtc always print a message like DTC: dts->dtb on file "dt.dtb.tmp" which cannot even be suppressed with "-qqq". To avoid incorrect MAKEALL status, we manually filter out this message. This is a bit complicated, as we have to make sure to set a correct return code. Also, get rid of the temp file: dtc accepts "-" for stdin. Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: Simon Glass <sjg@chromium.org> Acked-by: Simon Glass <sjg@chromium.org>

* fdt: Add support for embedded device tree (CONFIG_OF_EMBED)Simon Glass2011-10-26-0/+103
This new option allows U-Boot to embed a binary device tree into its image to allow run-time control of peripherals. This device tree is for U-Boot's own use and is not necessarily the same one as is passed to the kernel. The device tree compiler output should be placed in the $(obj) rooted tree. Since $(OBJCOPY) insists on adding the path to the generated symbol names, to ensure consistency it should be invoked from the directory where the .dtb file is located and given the input file name without the path.
