 There are two sources for the TF-A. Mainline and NXP. Get the one you prefer
 (support and features might differ).
 
+.. note::
+
+   If you are using GCC 12 and you get compiler/linker errors, try to add the
+   following arguments to your make command as workaround:
+   ``CFLAGS="-Wno-array-bounds" LDFLAGS="--no-warn-rwx-segments"``
