+BSP Related Configuration Options
+=================================
+
+This section describes configuration options related to the BSP.  Some
+configuration options may have a BSP-specific setting which is defined by
+``<bsp.h>``.  The BSP-specific settings can be disabled by the
+:ref:`CONFIGURE_DISABLE_BSP_SETTINGS` configuration option.
+
+.. index:: BSP_IDLE_TASK_BODY
+
+.. _BSP_IDLE_TASK_BODY:
+
+BSP_IDLE_TASK_BODY
+------------------
+
+CONSTANT:
+    ``BSP_IDLE_TASK_BODY``
+
+DATA TYPE:
+    Function pointer.
+
+RANGE:
+    Undefined or valid function pointer.
+
+DEFAULT VALUE:
+    This option is BSP specific.
+
+DESCRIPTION:
+    If ``BSP_IDLE_TASK_BODY`` is defined by the BSP and
+    ``CONFIGURE_IDLE_TASK_BODY`` is not defined by the application, then this
+    BSP specific idle task body will be used.
+
+NOTES:
+    As it has knowledge of the specific CPU model, system controller logic, and
+    peripheral buses, a BSP specific IDLE task may be capable of turning
+    components off to save power during extended periods of no task activity
+
+.. index:: BSP_IDLE_TASK_STACK_SIZE
+
+.. _BSP_IDLE_TASK_STACK_SIZE:
+
+BSP_IDLE_TASK_STACK_SIZE
+------------------------
+
+CONSTANT:
+    ``BSP_IDLE_TASK_STACK_SIZE``
+
+DATA TYPE:
+    Unsigned integer (``size_t``).
+
+RANGE:
+    Undefined or positive.
+
+DEFAULT VALUE:
+    This option is BSP specific.
+
+DESCRIPTION:
+    If ``BSP_IDLE_TASK_STACK_SIZE`` is defined by the BSP and
+    ``CONFIGURE_IDLE_TASK_STACK_SIZE`` is not defined by the application, then
+    this BSP suggested idle task stack size will be used.
+
+NOTES:
+    The order of precedence for configuring the IDLE task stack size is:
+
+    - RTEMS default minimum stack size.
+
+    - If defined, then ``CONFIGURE_MINIMUM_TASK_STACK_SIZE``.
+
+    - If defined, then the BSP specific ``BSP_IDLE_TASK_SIZE``.
+
+    - If defined, then the application specified ``CONFIGURE_IDLE_TASK_SIZE``.
+
+.. index:: BSP_INITIAL_EXTENSION
+
+.. _BSP_INITIAL_EXTENSION:
+
+BSP_INITIAL_EXTENSION
+---------------------
+
+CONSTANT:
+    ``BSP_INITIAL_EXTENSION``
+
+DATA TYPE:
+    List of user extension initializers (``rtems_extensions_table``).
+
+RANGE:
+    Undefined or a list of user extension initializers.
+
+DEFAULT VALUE:
+    This option is BSP specific.
+
+DESCRIPTION:
+    If ``BSP_INITIAL_EXTENSION`` is defined by the BSP, then this BSP specific
+    initial extension will be placed as the last entry in the initial extension
+    table.
+
+NOTES:
+    None.
+
+.. index:: BSP_INTERRUPT_STACK_SIZE
+
+.. _BSP_INTERRUPT_STACK_SIZE:
+
+BSP_INTERRUPT_STACK_SIZE
+------------------------
+
+CONSTANT:
+    ``BSP_INTERRUPT_STACK_SIZE``
+
+DATA TYPE:
+    Unsigned integer (``size_t``).
+
+RANGE:
+    Undefined or positive.
+
+DEFAULT VALUE:
+    This option is BSP specific.
+
+DESCRIPTION:
+    If ``BSP_INTERRUPT_STACK_SIZE`` is defined by the BSP and
+    ``CONFIGURE_INTERRUPT_STACK_SIZE`` is not defined by the application, then
+    this BSP specific interrupt stack size will be used.
+
+NOTES:
+    None.
+
+.. index:: BSP_MAXIMUM_DEVICES
+
+.. _BSP_MAXIMUM_DEVICES:
+
+BSP_MAXIMUM_DEVICES
+-------------------
+
+CONSTANT:
+    ``BSP_MAXIMUM_DEVICES``
+
+DATA TYPE:
+    Unsigned integer (``size_t``).
+
+RANGE:
+    Undefined or positive.
+
+DEFAULT VALUE:
+    This option is BSP specific.
+
+DESCRIPTION:
+    If ``BSP_MAXIMUM_DEVICES`` is defined by the BSP and
+    ``CONFIGURE_MAXIMUM_DEVICES`` is not defined by the application, then this
+    BSP specific maximum device count will be used.
+
+NOTES:
+    This option is specific to the device file system (devFS) and should not be
+    confused with the ``CONFIGURE_MAXIMUM_DRIVERS`` option.  This parameter
+    only impacts the devFS and thus is only used by ``<rtems/confdefs.h>`` when
+    ``CONFIGURE_USE_DEVFS_AS_BASE_FILESYSTEM`` is specified.
+
+.. index:: CONFIGURE_BSP_PREREQUISITE_DRIVERS
+
+.. _CONFIGURE_BSP_PREREQUISITE_DRIVERS:
+
+CONFIGURE_BSP_PREREQUISITE_DRIVERS
+----------------------------------
+
+CONSTANT:
+    ``CONFIGURE_BSP_PREREQUISITE_DRIVERS``
+
+DATA TYPE:
+    List of device driver initializers (``rtems_driver_address_table``).
+
+RANGE:
+    Undefined or array of device drivers.
+
+DEFAULT VALUE:
+    This option is BSP specific.
+
+DESCRIPTION:
+    ``CONFIGURE_BSP_PREREQUISITE_DRIVERS`` is defined if the BSP has device
+    drivers it needs to include in the Device Driver Table.  This should be
+    defined to the set of device driver entries that will be placed in the
+    table at the *FRONT* of the Device Driver Table and initialized before any
+    other drivers *INCLUDING* any application prerequisite drivers.
+
+NOTES:
+    ``CONFIGURE_BSP_PREREQUISITE_DRIVERS`` is typically used by BSPs to
+    configure common infrastructure such as bus controllers or probe for
+    devices.
+
+.. index:: CONFIGURE_DISABLE_BSP_SETTINGS
+
+.. _CONFIGURE_DISABLE_BSP_SETTINGS:
+
+CONFIGURE_DISABLE_BSP_SETTINGS
+------------------------------
+
+CONSTANT:
+    ``CONFIGURE_DISABLE_BSP_SETTINGS``
+
+DATA TYPE:
+    Boolean feature macro.
+
+RANGE:
+    Defined or undefined.
+
+DEFAULT VALUE:
+    This is not defined by default.
+
+DESCRIPTION:
+    All BSP specific configuration settings can be disabled by the application
+    with the ``CONFIGURE_DISABLE_BSP_SETTINGS`` option.
+
+NOTES:
+    None.
+
+.. index:: CONFIGURE_MALLOC_BSP_SUPPORTS_SBRK
+
+.. _CONFIGURE_MALLOC_BSP_SUPPORTS_SBRK:
+
+CONFIGURE_MALLOC_BSP_SUPPORTS_SBRK
+----------------------------------
+
+CONSTANT:
+    ``CONFIGURE_MALLOC_BSP_SUPPORTS_SBRK``
+
+DATA TYPE:
+    Boolean feature macro.
+
+RANGE:
+    Defined or undefined.
+
+DEFAULT VALUE:
+    This option is BSP specific.
+
+DESCRIPTION:
+    This configuration parameter is defined by a BSP to indicate that it does
+    not allocate all available memory to the C Program Heap used by the Malloc
+    Family of routines.
+
+    If defined, when ``malloc()`` is unable to allocate memory, it will call
+    the BSP supplied ``sbrk()`` to obtain more memory.
+
+NOTES:
+    This parameter should not be defined by the application. Only the BSP knows
+    how it allocates memory to the C Program Heap.
