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

2024-10-30T19:02:53+00:00

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.

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

2024-03-01T14:53:47+00:00

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.

Explicitly mark the regex string as raw string to avoid the warning.

Allow Python packages to be dropped

2023-09-21T22:03:46+00:00

When building in a portage chroot, we do not have the environment needed
to build pylibfdt. It is instead build as a separate package.

Provide a build option to tell U-Boot to skip this part of the build. We
still need it to use binman, etc. but don't need it to build its
dependencies.

pylibfdt: Allow version normalization to fail

2023-01-07T23:02:26+00:00

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

2023-01-06T13:14:19+00:00

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. [2]

fdt: Move to setuptools

2022-10-29T13:36:33+00:00

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.

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.
