+
+VALUE CONSTRAINTS:
+    The value of this configuration option shall satisfy all of the following
+    constraints:

+DESCRIPTION:
+    The value of this configuration option defines the task storage size of the

+
+NOTES:
+    A task storage area of the specified size is statically allocated for the
+    Classic API initialization task.  It is defined by ``<rtems/confdefs.h>`.
+
+    If this configuration option is specified, then a maximum thread-local
+    storage size defined by :ref:`CONFIGURE_MAXIMUM_THREAD_LOCAL_STORAGE_SIZE` is used for
+    the Classic API initialization task.
+
+    If this configuration option is specified, then the Classic API
+    initialization task should be accounted for in
+    :ref:`CONFIGURE_MINIMUM_TASKS_WITH_USER_PROVIDED_STORAGE`.
