+ * Name:  kinetis_spi/ssp0/ssp1select, kinetis_spi/ssp0/ssp1status, and

+ *
+ * Description:
+ *   These external functions must be provided by board-specific logic.  They are
+ *   implementations of the select, status, and cmddata 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 Kinetis logic.  To use
+ *   this common SPI logic on your board:
+ *
+ *   1. Provide logic in kinetis_boardinitialize() to configure SPI/SSP chip select
+ *      pins.
+ *   2. Provide kinetis_spi/ssp0/ssp1select() and kinetis_spi/ssp0/ssp1status() functions
+ *      in your board-specific logic.  These functions will perform chip selection
+ *      and status operations using GPIOs in the way your board is configured.
+ *   2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
+ *      kinetis_spi/ssp0/ssp1cmddata() functions in your board-specific logic.  These
+ *      functions will perform cmd/data selection operations using GPIOs in the way
+ *      your board is configured.
+ *   3. Add a call 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).
