What is the motivation for this? I worry that we might end up with a lot of files in one directory. One benefit of the current approach is that .dts files are split up by vendor. Even if we put the SoC .dtsi files in arch/arm, perhaps there is a benefit in leaving the board .dts files in board/<vendor>? I don't have strong feelings, just questing this...

Linux v3.13 has 500 .dtsi and .dts files in arch/arm/boot/dts/ and they are still adding device trees to that directory. I have no idea if they will keep going, or someone will scream and turn around. Anyway, when Linux guys someday invents a nice idea to work arond increasing device trees, we can import it to U-Boot. It should be easy for us because we already have a similar build system. > One benefit of the current approach is > that .dts files are split up by vendor.

Now Xilinx has device trees both for ARM and Microblaze, resulting in totally unrelated device trees in one directory. What if Freescale decided to adopt device tree? They support various boards on ARM, PowerPC, M68K. Renesus is the same. They have ARM and SuperH boards. On the other hand, different vendors can produce similar boards. For example avionic design, which develops Tegra boards, are using nVidia's sources. When I saw board/nvidia/common/common.mk and board/avionic-design/*/Makefile, etc., I think we're screwed up with <vendor> directory. Best Regards Masahiro Yamada

Having all the device trees in one place (I don't even see why it should be split by arch; some common dtsi files may be shared by multiple arches) is nice for grepping and maintenance. If it gets too large it can grow an internal hierarchy. Just like net drivers go under drivers/net regardless of arch, etc. -Scott

Hmm, but would it be such a big problem to keep the general ARM and SOC stuff in arch/arm/dts and the board-specific stuff in board/ ? One of the problems with Linux is that their board-specific code is spread all over the place, and I'm not sure we want to emulate it? > >> One benefit of the current approach is >> that .dts files are split up by vendor.

They have ARM and SuperH boards. I'm not convinced yet. I think maybe you have forgotten about the .dtsi files for SoCs. They are common, but no one is going to include a board .dts file (nor can they), so putting them in a common area does not seem like a win to me. > > > On the other hand, different vendors can produce similar boards. > For example avionic design, which develops Tegra boards, > are using nVidia's sources. > > When I saw board/nvidia/common/common.mk > and board/avionic-design/*/Makefile, etc., I think we're screwed up > with <vendor> directory. Well the probably as I see it is that board/nvidia has some SoC code that other boards want to use. The solution to that might be to move the code to arch/arm/cpu/armv7/tegra... instead? > > Best Regards > Masahiro Yamada > Regards, Simon

Opposite. Board-specific code mostly resides under arch/arm/mach-* or arch/arm/plat-*. And what else is arch/arm/configs and arch/arm/boot/dts. That's it. We have board-specific part - entries in boards.cfg - include/configs/<board_config>.h - board/<vendor>/<board> or board/<board> - arch/<ARCH>/include/am/arch-<soc> includes sometimes board-specific headers as well as SoC specific headers. (Because there is no other place to store board-specific header files) Various stuff under include/, for exmple - include/xilinx.h: vendor specific? - include/sandboxblockdev.h: arch specific? And we often missed to remove remainders of dead boards. U-Boot has more troublesome directory structure. > >> One benefit of the current approach is > >> that .dts files are split up by vendor.

I do know that *.dtsi files are included from others, while *.dts files are not included from anywhere. And I understand your policy, *.dtsi to arch dir and *.dts to vendor dir. (No that I care, we have two exceptions: ./board/avionic-design/dts/tegra20-tamonten.dtsi ./board/avionic-design/dts/tegra30-tamonten.dtsi) If I have to mention a win, we can save makefiles by not putting almost same ones in vendor directories. Anyway, we have 3 structures proposed so far. [1] board/$(VENDOR)/dts/ (current structure) [2] arch/$(ARCH)/dts/ (suggested by me) [3] dts/ for all architectures (suggested by Scott) In my option, [2] and [3] seem to be reasonable enough. If we cannot reach an agreement, shall we postpone 2/3 and 3/3 and apply only 1/3? > > On the other hand, different vendors can produce similar boards. > > For example avionic design, which develops Tegra boards, > > are using nVidia's sources. > > > > When I saw board/nvidia/common/common.mk > > and board/avionic-design/*/Makefile, etc., I think we're screwed up > > with <vendor> directory. > > Well the probably as I see it is that board/nvidia has some SoC code > that other boards want to use.

Concerning the result, board/nvidia/common turned out to be SoC-specific code, not Vendor-specific (board-specific) code. But I guess the difference between SoC-specific code and board-specific code was not clear when nVidia develpers posted that code first. Maybe I am digressing, but it also happens to me quite often. It is difficult for me to decide whether each code should go to board/panasonic or arch/arm/cpu/armv7/uniphier. I'd say, vendor (and board) directories are harmful. Best Regards Masahiro Yamada

This, I think is backwards. Xilinx has (and Freescale and others are or will be joining them) a lot of things shared between them as IP blocks get reused from non-ARM to ARM CPUs. So there's a level of DT sharing for these blocks between the CPUs. The kernel is going to start having this problem as vendors start dropping their arm IP blocks into ARMv8 SoCs, and those would be in arch/arm64/. The question is, will people care enough about the duplication, or just live with it.

The question is, will people > care enough about the duplication, or just live with it. We share all soft IP drivers between ARM and Microblaze and we will continue in this style. The point is to have the same binding which we have. We are using device-tree generator to get the latest binding which is in sync with kernel. When we adopt u-boot configured by device-tree (when variable handling in u-boot is fixed) we will use the same binding in uboot too. I personally don't care where DTS files will be placed because we will generate them as we are doing now. Thanks, Michal

Normally they would provide a set of .dtsi files, say for example tegra20.dtsi, tegra30.dtsi, etc. It makes sense to have a common SoC directory that all boards can use. Then a board that uses say a Tegra SoC on it can just include those files and connect things up as required. > >> > >> > What if Freescale decided to adopt device tree? >> > They support various boards on ARM, PowerPC, M68K. >> > >> > Renesus is the same.

Interesting...the idea with board files I think is that it is for code specific to a board. My hope is that there would be less of that with device tree, but it is early days. You are right about the common directory in board/<vendor>. But this is probably worth a wider discussion than just device tree files. Regards, Simon

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.
