* dtc: Switch to building and using our own dtc unless providedTom Rini2017-09-241-0/+4
| | | | | | | | | | This makes us act like the Linux Kernel does and allow for dtc to be provided externally but otherwise we use the version of dtc that is included in the sources. This in turn means that we can drop the checkdtc logic. We select DTC in the cases where we will need the dtc tool provided. Signed-off-by: Tom Rini <trini@konsulko.com>
* spl: dm: Kconfig: split OF_CONTROL and OF_PLATDATA between SPL and TPLPhilipp Tomsich2017-08-131-0/+29
| | | | | | | | | | | | | | | For the RK3368, we want to use OF_PLATDATA in TPL, but full OF_CONTROL in SPL: this requires the introduction of a new family of configuration options to decouple SPL_OF_CONTROL and SPL_OF_PLATDATA from TPL. Consequently, Makefile.spl needs to be adjusted to test for these configuration items through the $(SPL_TPL_) macro instead of hard-coding the SPL variant.

* Allow boards to initialize the DT at runtime.Alex Deymo2017-05-091-0/+8
| | | | | | | | | | | | | | | | | In some boards like the Raspberry Pi the initial bootloader will pass a DT to the kernel. When using U-Boot as such kernel, the board code in U-Boot should be able to provide U-Boot with this, already assembled device tree blob. This patch introduces a new config option CONFIG_OF_BOARD to use instead of CONFIG_OF_EMBED or CONFIG_OF_SEPARATE which will initialize the DT from a board-specific funtion instead of bundling one with U-Boot or as a separated file. This allows boards like the Raspberry Pi to reuse the device tree passed from the bootcode.bin and start.elf firmware files, including the run-time selected device tree overlays.

* dm: Add callback to modify the device treemario.six@gdsys.cc2017-03-231-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | Certain boards come in different variations by way of utilizing daughter boards, for example. These boards might contain additional chips, which are added to the main board's busses, e.g. I2C. The device tree support for such boards would either, quite naturally, employ the overlay mechanism to add such chips to the tree, or would use one large default device tree, and delete the devices that are actually not present. Regardless of approach, even on the U-Boot level, a modification of the device tree is a prerequisite to have such modular families of boards supported properly. Therefore, we add an option to make the U-Boot device tree (the actual copy later used by the driver model) writeable, and add a callback method that allows boards to modify the device tree at an early stage, at which, hopefully, also the application of device tree overlays will be possible.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit changes the working directory where the build process occurs. Before this commit, build process occurred under the source tree for both in-tree and out-of-tree build. That's why we needed to add $(obj) prefix to all generated files in makefiles like follows: $(obj)u-boot.bin: $(obj)u-boot Here, $(obj) is empty for in-tree build, whereas it points to the output directory for out-of-tree build. And our old build system changes the current working directory with "make -C <sub-dir>" syntax when descending into the sub-directories. On the other hand, Kbuild uses a different idea to handle out-of-tree build and directory descending. The build process of Kbuild always occurs under the output tree. When "O=dir/to/store/output/files" is given, the build system changes the current working directory to that directory and restarts the make. Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>" syntax for descending into sub-directories. (We can write it like "make $(obj)=<sub-dir>" with a shorthand.)

| | | | | | | | | | | | | | | | | | | | | | | 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.
