pylibfdt: setup.py: Drop license_files

2025-08-07T17:16:12Z

On more recent versions of setuptools the warning about not being able to find the files specified in license_files has re-appeared. This is because as best I can tell, it can't and won't look in $(srctree) but rather only subdirectories of scripts/dtc/pylibfdt. Since we already provide both SPDX tags and a license field with the SPDX contents, let us just drop license_files as it's not mandatory. Signed-off-by: Tom Rini

pylibfdt: correct license information (further)

2025-06-26T18:10:58Z

Since commit 51ec8db23280 ("pylibfdt: correct license information"), the License classifiers are gone so I assume setuptools now extract the license from the license argument to setuptools.setup() function. It's always been incorrect as far as I could tell, so let's fix this with the appropriate info from the SPDX License identifier at the top of the file. It was missing GPL-2.0-or-later and we disambiguate by using BSD-2-Clause instead of simply BSD. Fixes: 6b08fb5cc44f ("fdt: Move to setuptools") Signed-off-by: Quentin Schulz

scripts/dtc/pylibfdt/libfdt.i_shipped: Use SWIG_AppendOutput

2024-10-30T19:02:53Z

Swig has changed language specific AppendOutput functions. The helper macro SWIG_AppendOutput remains unchanged. Use that instead of SWIG_Python_AppendOutput, which would require an extra parameter since swig 4.3.0. /home/flk/poky/build-test/tmp/work/qemux86_64-poky-linux/u-boot/2024.10/git/arch/x86/cpu/u-boot-64.lds | scripts/dtc/pylibfdt/libfdt_wrap.c: In function ‘_wrap_fdt_next_node’: | scripts/dtc/pylibfdt/libfdt_wrap.c:5581:17: error: too few arguments to function ‘SWIG_Python_AppendOutput’ | 5581 | resultobj = SWIG_Python_AppendOutput(resultobj, val); | | ^~~~~~~~~~~~~~~~~~~~~~~~ Signed-off-by: Markus Volk Reported-by: Rudi Heitbaum Link: https://github.com/dgibson/dtc/pull/154

pylibfdt: Fix "invalid escape sequence '\w'" in setup.py

Once u-boot's build system invokes python3 scripts/dtc/pylibfdt/setup.py --quiet build_ext --inplace it may fail with scripts/dtc/pylibfdt/setup.py:40: SyntaxWarning: invalid escape sequence '\w' RE_KEY_VALUE = re.compile('(?P\w+) *(?P[+])?= *(?P.*)$') depending on the used Python version.

pylibfdt: Allow version normalization to fail

2023-01-07T23:02:26Z

In some cases, we might not have the sic portion of setuputils available. Make our import and use of this be done in try/except blocks as this is done to suppress a run-time warning that is otherwise non-fatal.

pylibfdt: Fix disable version normalization

2023-01-06T13:14:19Z

On Arch Linux based systems python setuptools does not contain "setuptools.extern" hence it is failing with the following error-message: " ModuleNotFoundError: No module named 'setuptools.extern' " According to a eschwartz `setuptools.extern` is not a public API and shall not be assumed to be present in the setuptools package. He mentions that the setuptools project anyway wants to drop this. [1] Use the correct solution introduced by python setuptools developers to disable normalization.

fdt: Move to setuptools

2022-10-29T13:36:33Z

The distutils package is deprecated. The upstream libfdt repo uses setuptools for building the pylibfdt module, so bring in that code, suitably modified for U-Boot. Also bring in the README. The modifications include setting the version correctly, making use of the environment variables provided by the Makefile and various tweaks to the directories. Note that the version omits the minus character at the start of EXTRAVERSION, since this creates a warning. The build is really just used within U-Boot itself, so it doesn't matter too much if the version matches upstream, or exactly matches U-Boot. Signed-off-by: Simon Glass

libfdt: Fix build with python 3.10

Python 3.10 requires defining PY_SSIZE_T_CLEAN. This will be fixed in swig 4.10 but it is not clear when it will be released. There was a warning since python 3.8. Link: https://github.com/swig/swig/pull/2277 Signed-off-by: Michal Suchanek Reviewed-by: Simon Glass
