+ * Description:
+ *   The external functions, lpc17_ssp0/1/2select and lpc17_ssp0/1/2status 
+ *   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 lpc17_sspinitialize())
+ *   are provided by common LPC17xx logic.  To use this common SPI logic on your
+ *   board:
+ *
+ *   1. Provide logic in lpc17_boardinitialize() to configure SPI/SSP chip select
+ *      pins.
+ *   2. Provide lpc17_ssp0/1/2select() and lpc17_ssp0/1/2status() 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 lpc17_sspinitialize() in your low level application
+ *      initialization logic
+ *   4. The handle returned by lpc17_sspinitialize() 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).
