+-------------------------------------------
+
+.. rubric:: CONSTANT:
+
+``CONFIGURE_MAXIMUM_THREAD_LOCAL_STORAGE_SIZE``
+
+.. rubric:: OPTION TYPE:
+
+This configuration option is an integer define.
+
+.. rubric:: DEFAULT VALUE:
+
+The default value is 0.
+
+.. rubric:: DESCRIPTION:
+
+If the value of this configuration option is greater than zero, then it
+defines the maximum thread-local storage size, otherwise the thread-local
+storage size is defined by the linker depending on the thread-local storage
+objects used by the application in the statically-linked executable.
+
+.. rubric:: NOTES:
+
+This configuration option can be used to reserve space for the dynamic linking
+of modules with thread-local storage objects.
+
+If the thread-local storage size defined by the thread-local storage
+objects used by the application in the statically-linked executable is greater
+than a non-zero value of this configuration option, then a fatal error will
+occur during system initialization.
+
+Use :c:func:`RTEMS_ALIGN_UP` and
+:c:macro:`RTEMS_TASK_STORAGE_ALIGNMENT` to adjust the size to meet the
+minimum alignment requirement of a thread-local storage area.
+
+The actual thread-local storage size is determined when the application
+executable is linked.  The ``rtems-exeinfo`` command line tool included in
+the RTEMS Tools can be used to obtain the thread-local storage size and
+alignment of an application executable.
+
+.. rubric:: CONSTRAINTS:
+
+The following constraints apply to this configuration option:
+
+* The value of the configuration option shall be greater than or equal to zero.
+
+* The value of the configuration option shall be less than or equal to
+  `SIZE_MAX <https://en.cppreference.com/w/c/types/limits>`_.
+
+* The value of the configuration option shall be an integral multiple of
+  :c:macro:`RTEMS_TASK_STORAGE_ALIGNMENT`.
