 * 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/spi.h). All other methods (including hcs12_spibus_initialize())
 *   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 hcs12_spibus_initialize() in your low level application
 *      initialization logic
 *   4. The handle returned by hcs12_spibus_initialize() 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).
