+Subject: [PATCH] pylibfdt: Replace removed SWIG Python 2 compatibility macros
+
+SWIG 4.5.0 removed Python 2 compatibility macros (PyInt_*, PyString_*)
+from its runtime header pyhead.swg (see commit 79f7a2b7cb7d). Replace
+them with their Python 3 C API equivalents:
+
+- PyString_FromString -> PyUnicode_FromString
+- PyString_AsString -> PyBytes_AsString
+- PyInt_AsLong -> PyLong_AsLong
+
+The replacements are safe since the macros were already aliased to
+these exact functions in SWIG's Python 3 code path.
+
+This is a backport of dtc commit 5008d1d6a356 ("pylibfdt: Replace
+removed SWIG Python 2 compatibility macros").

SWIG 4.5.0 removed Python 2 compatibility macros (PyInt_*, PyString_*) from its runtime. Backport the dtc upstream fix to u-boot's bundled pylibfdt/libfdt.i_shipped to replace them with Python 3 equivalents.
