+ *   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 LPC313X logic.  To use this common SPI logic on your
+ *   board:
+ *
+ *   1. Provide logic in lpc313x_boardinitialize() to configure SPI chip select
+ *      pins.
+ *   2. Provide lpc313x_spiselect() and lpc313x_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).
