This commit moves: CONFIG_OF_CONTROL CONFIG_OF_SEPARATE CONFIG_OF_EMBED CONFIG_OF_HOSTFILE Because these options are currently not supported for SPL, the "Device Tree Control" menu does not appear in the SPL configuration. Note: zynq-common.h should be adjusted so as not to change the default value of CONFIG_SPL_FAT_LOAD_PAYLOAD_NAME. Signed-off-by:

In some cases, an externally-built device tree binary is required to be attached to U-Boot. An example is when using image signing, since in that case the .dtb file must include the public keys. Add a DEV_TREE_BIN option to the Makefile, and update the documentation. Usage is something like: make DEV_TREE_BIN=boot/am335x-boneblack-pubkey.dtb Signed-off-by:

Unlike Linux Kernel, U-Boot historically had *.dts files under board/$(VENDOR)/dts/ and *.dtsi files under arch/$(ARCH)/dts/. I think arch/$(ARCH)/dts dicretory is a better location to store both *.dts and *.dtsi files. For example, before this commit, board/xilinx/dts directory had both Microblaze dts (microblaze-generic.dts) and ARM dts (zynq-*.dts), which are totally unrelated. This commit moves *.dts to arch/$(ARCH)/dts/ directories, allowing us to describe nicely mutiple DTBs generation in the next commit. Signed-off-by:

This commit refactors cleaning targets such as clean, clobber, mrpropper, distclean with scripts/Makefile.clean.

Now we are ready to switch over to real Kbuild. This commit disables temporary scripts: scripts/{Makefile.build.tmp, Makefile.host.tmp} and enables real Kbuild scripts: scripts/{Makefile.build,Makefile.host,Makefile.lib}. This switch is triggered by the line in scripts/Kbuild.include -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj We need to adjust some build scripts for U-Boot. But smaller amount of modification is preferable. Additionally, we need to fix compiler flags which are locally added or removed. In Kbuild, it is not allowed to change CFLAGS locally. Instead, ccflags-y, asflags-y, cppflags-y, CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o are prepared for that purpose. Signed-off-by:

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.) This means the current working directory is always the top of the output directory. Signed-off-by:

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. Signed-off-by:

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 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.

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.

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.'

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:

Commit 896bbb53 "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.

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:

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.
