dtc: Update the build rule for pylibfdt

2021-04-06T04:33:10+00:00

Some versions of make complain about using a grouped target without a
recipe:

.../pylibfdt/Makefile:36: *** grouped targets must provide a recipe.  Stop.

Fix this by adding a dummy recipe.

libfdt: Tidy up pylibfdt build rule

2021-03-26T04:03:04+00:00

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.

binman: Adjust pylibfdt for incremental build

2020-07-25T01:25:15+00:00

If the pylibfdt shared-object file is detected, then Python assumes that
the libfdt.py file exists also.

Sometimes when an incremental build aborts, the shared-object file is
built but the libfdt.py is not. The only way out at this point is to use
'make mkproper', or similar.

Fix this by removing the .so file before it is built. This seems to make
Python rebuild everything.

pylibfdt: Use Python 2 in Makefile

2019-01-15T20:28:45+00:00

pylibfdt needs Python 2 to build.
Replace $(PYTHON) with $(PYTHON2) in pylibfdt Makefile
to ensure Python 2 is used to build it.

This fixes build on systems where Python 3 is the default version
of the "python" interpreter.

pylibfdt: move pylibfdt to scripts/dtc/pylibfdt and refactor makefile

2017-11-17T12:43:32+00:00

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.
