+ * The external functions, tiva_spiselect, tiva_spistatus, and
+ * tiva_spicmddata must be provided by board-specific logic. These are
+ * implementations of the select, status, and cmddata methods of the SPI
+ * interface defined by struct spi_ops_s (see include/nuttx/spi/spi.h).
+ * All other methods (including up_spiinitialize()) are provided by common
+ * logic. To use this common SPI logic on your board:
+ *
+ * 1. Provide logic in tiva_boardinitialize() to configure SPI chip select
+ * pins.
+ * 2. Provide tiva_spiselect() and tiva_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. If CONFIG_SPI_CMDDATA is defined in your NuttX configuration, provide
+ * the tiva_spicmddata() function in your board-specific logic. This
+ * functions will perform cmd/data selection operations using GPIOs in
+ * the way your board is configured.
+ * 4. Add a call to up_spiinitialize() in your low level application
+ * initialization logic
+ * 5. 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).
