2019-03-22Revert "Ensure device tree DTS is compiled"Masahiro Yamada
This reverts commit 27cb7300ffda7a3f1581f0f5a2d3bfe59b97ad67. I am not sure if I correctly understood the log of commit 27cb7300ffda ("Ensure device tree DTS is compiled"), but the code-diff looks like it was trying to solve the missed re-compilation when .dts was modified. Recently, commit 2737dfe096b6 ("kbuild: make arch-dtbs target PHONY") fixed the issue in a more correct and more complete way. Anyway, since the former commit, we see a clumsy log like this: make[2]: 'arch/sandbox/dts/sandbox.dtb' is up to date Another problem is, it created multiple paths to descend into arch/*/dts/, causing a race in parallel building. So, let's revert it. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2019-01-15kbuild: add .SECONDARY special target to scripts/Kbuild.includeMasahiro Yamada
Based on the following Linux commits: - 54a702f70589 ("kbuild: mark $(targets) as .SECONDARY and remove .PRECIOUS markers") - 8e9b61b293d9 ("kbuild: move .SECONDARY special target to Kbuild.include") GNU Make automatically deletes intermediate files that are updated in a chain of pattern rules. Example 1) %.dtb.o <- %.dtb.S <- %.dtb <- %.dts Example 2) %.o <- %.c <- %.c_shipped A couple of makefiles mark such targets as .PRECIOUS to prevent Make from deleting them, but the correct way is to use .SECONDARY. .SECONDARY Prerequisites of this special target are treated as intermediate files but are never automatically deleted. .PRECIOUS When make is interrupted during execution, it may delete the target file it is updating if the file was modified since make started. If you mark the file as precious, make will never delete the file if interrupted. Both can avoid deletion of intermediate files, but the difference is the behavior when Make is interrupted; .SECONDARY deletes the target, but .PRECIOUS does not. The use of .PRECIOUS is relatively rare since we do not want to keep partially constructed (possibly corrupted) targets. .SECONDARY with no prerequisites causes all targets to be treated as secondary. This agrees the policy of Kbuild. scripts/Kbuild.include seems a suitable place to add it because it is included from almost all sub-makes.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

With commit 9bd76b807636 ("spl: make CONFIG_OF_EMBED pass dts through fdtgrep"), CONFIG_SPL_MULTI_DTB_FIT has been broken because cmd_fdtgrep was now unknown in scripts/Makefile.spl after moving it to dts/Makefile.

2017-11-29spl: make CONFIG_OF_EMBED pass dts through fdtgrepGoldschmidt Simon
Building spl with CONFIG_OF_EMBED enabled results in an error message on my board: "SPL image too big". This is because the fdtgrep build step is only executed for CONFIG_OF_SEPARATE. Fix this by moving the fdtgrep build step ('cmd_fdtgreo') from scripts/Makefile.spl to dts/Makefile so that the reduced dtb is available for all kinds of spl builds. The resulting variable name for the embedded device tree blob changes, too, which is why common.h and fdtdec.c have tiny changes.

2017-11-17pylibfdt: compile pylibfdt only when dtoc/binman is necessaryMasahiro Yamada
Currently, pylibfdt is always compiled if swig is installed on your machine. It is really annoying because most of targets (excepts x86, sunxi, rockchip) do not use dtoc or binman. "checkbinman" and "checkdtoc" are wrong. It is odd that the final build stage checks if we have built necessary tools. If your platform depends on dtoc/binman, you must be able to build pylibfdt. If swig is not installed, it should fail immediately. I added PYLIBFDT, DTOC, BINMAN entries to Kconfig. They should be property select:ed by platforms that need them. Kbuild will descend into scripts/dtc/pylibfdt/ only when CONFIG_PYLIBFDT is enabled. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2017-05-09Allow boards to initialize the DT at runtime.Alex Deymo
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.

2017-03-23dm: Add callback to modify the device treemario.six@gdsys.cc
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.
