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

2022-10-29T13:36:33Z

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

pylibfdt: Rework "avoid unused variable warning" lines

2021-05-24T15:47:44Z

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.

dtc: Update the build rule for pylibfdt

2021-04-06T04:33:10Z

libfdt: Tidy up pylibfdt build rule

2021-03-26T04:03:04Z

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

libfdt: Detected out-of-space with fdt_finish()

2020-09-22T18:50:43Z

At present the Python sequential-write interface can produce an error when it calls fdt_finish(), since this needs to add a terminating tag to the end of the struct section. Fix this by automatically expanding the buffer if needed. Signed-off-by: Simon Glass
