+ * Name:  hcs12_spiselect and hcs12_spistatus
+ *
+ * Description:
+ *   The external functions, hcs12_spiselect and hcs12_spistatus must be
+ *   provided by board-specific logic.  They are implementations of the select
+ *   and status methods of the SPI interface defined by struct spi_ops_s (see
+ *   include/nuttx/spi.h). All other methods (including up_spiinitialize())
+ *   are provided by common HCS12 logic.  To use this common SPI logic on your
+ *   board:
+ *
+ *   1. Provide logic in hcs12_boardinitialize() to configure SPI chip select
+ *      pins.
+ *   2. Provide hcs12_spiselect() and hcs12_spistatus() functions in your
+ *      board-specific logic.  These functions will perform chip selection and
+ *      status operations using GPIOs in the way your board is configured.
+ *   3. Add a calls to up_spiinitialize() in your low level application
+ *      initialization logic
+ *   4. The handle returned by up_spiinitialize() may then be used to bind the
+ *      SPI driver to higher level logic (e.g., calling
+ *      mmcsd_spislotinitialize(), for example, will bind the SPI driver to
+ *      the SPI MMC/SD driver).
