* pylibfdt: Rework "avoid unused variable warning" linesTom Rini2021-05-241-2/+2
| | | | | | | | | | | Clang has -Wself-assign enabled by default under -Wall and so when building with -Werror we would get an error here. Inspired by Linux kernel git commit a21151b9d81a ("tools/build: tweak unused value workaround") make use of the fact that both Clang and GCC support casting to `void` as the method to note that something is intentionally unused.

| | | | | | | | | | | | | | At present the build rule for pylibfdt depends on _libfdt.so but modern Python versions add a different suffix to the output file, resulting in something like _libfdt.cpython-38-x86_64-linux-gnu.so The result is that pylibfdt is rebuilt every time. Rename the file the standard name so that the rule works correctly. Also add libfdt.py to the dependencies, so that file is always created if missing. Signed-off-by: Simon Glass <sjg@chromium.org>

* dtc: add ability to make nodes conditional on them being referencedMaxime Ripard2020-02-055-0/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is needed when importing mainline DTs into U-Boot, as some started using this /omit-if-no-ref/ tag, so won't compile with U-Boot's current dtc copy. This is just a cherry-pick of the patch introducing this feature. Original commit message from Maxime: ------------------ A number of platforms have a need to reduce the number of DT nodes, mostly because of two similar constraints: the size of the DT blob, and the time it takes to parse it. As the DT is used in more and more SoCs, and by more projects, some constraints start to appear in bootloaders running from SRAM with an order of magnitude of 10kB. A typical DT is in the same order of magnitude, so any effort to reduce the blob size is welcome in such an environment. Some platforms also want to reach very fast boot time, and the time it takes to parse a typical DT starts to be noticeable. Both of these issues can be mitigated by reducing the number of nodes in the DT. The biggest provider of nodes is usually the pin controller and its subnodes, usually one for each valid pin configuration in a given SoC. Obviously, a single, fixed, set of these nodes will be used by a given board, so we can introduce a node property that will tell the DT compiler to drop the nodes when they are not referenced in the tree, and as such wouldn't be useful in the targetted system.

* libfdt: Revert 6dcb8ba4 from upstream libfdtTom Rini2020-01-302-42/+11
| | | | | | | | | | | | | | | | | | | | | | In upstream libfdt, 6dcb8ba4 "libfdt: Add helpers for accessing unaligned words" introduced changes to support unaligned reads for ARM platforms and 11738cf01f15 "libfdt: Don't use memcpy to handle unaligned reads on ARM" improved the performance of these helpers. In practice however, this only occurs when the user has forced the device tree to be placed in memory in a non-aligned way, which in turn violates both our rules and the Linux Kernel rules for how things must reside in memory to function. This "in practice" part is important as handling these other cases adds visible (1 second or more) delay to boot in what would be considered the fast path of the code.

* libfdt: Allow #size-cells of 0Matthias Brugger2019-10-151-3/+5
| | | | | | | | | | | | | | | | | | | | The commit "libfdt: fdt_address_cells() and fdt_size_cells()" introduced a bug as it consolidated code between the helpers for getting be 0, and is frequently found so in practice for /cpus. IEEE1275 only requires implementations to handle 1..4 for #address-cells, although one could make a case for #address-cells == #size-cells == 0 being used to represent a bridge with a single port. While we're there, it's not totally obvious that the existing implicit cast of a u32 to int will give the correct results according to strict C, although it does work in practice. Straighten that up to cast only after we've made our range checks.

| | | | | | | | | | | | | | | | The new fdt_generate_phandle() function can be used to generate a new, unused phandle given a specific device tree blob. The implementation is somewhat naive in that it simply walks the entire device tree to find the highest phandle value and then returns a phandle value one higher than that. A more clever implementation might try to find holes in the current set of phandle values and fill them. But this implementation is relatively simple and works reliably.

* SPDX: Convert all of our multiple license tags to Linux Kernel styleTom Rini2018-05-071-2/+1
| | | | | | | | | | | | | | | | | | | | | | | 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 multiple licenses (in these cases, dual license) declared in the SPDX-License-Identifier tag. In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B" as per the Linux Kernel style document. Note that parenthesis are allowed so when they were used before we continue to use them. Reviewed-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Tom Rini <trini@konsulko.com>

* pylibfdt: compile pylibfdt only when dtoc/binman is necessaryMasahiro Yamada2017-11-171-1/+1
| | | | | | | | | | | | | | | | | | 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>
* pylibfdt: move pylibfdt to scripts/dtc/pylibfdt and refactor makefileMasahiro Yamada2017-11-175-0/+609
| | | | | | | | | | | | | | | | | | | | | The pylibfdt is used by dtoc (and, indirectly by binman), but there is no reason why it must be generated in the tools/ directory. Recently, U-Boot switched over to the bundled DTC, and the directory structure under scripts/dtc/ now mirrors the upstream DTC project. So, scripts/dtc/pylibfdt is the best location. I also rewrote the Makefile in a cleaner Kbuild style. The scripts from the upstream have been moved as follows: lib/libfdt/pylibfdt/setup.py -> scripts/dtc/pylibfdt/setup.py lib/libfdt/pylibfdt/libfdt.i -> scripts/dtc/pylibfdt/libfdt.i_shipped The .i_shipped is coped to .i during building because the .i must be located in the objtree when we build it out of tree.
