+ * The external functions, stm32_spi1/2select and stm32_spi1/2status must be

+ * provided by board-specific logic.  These are implementations of the

+ * select and status methods SPI interface defined by struct spi_ops_s (see

+ * include/nuttx/spi.h). All other methods (including up_spiinitialize())

+ * are provided by common logic.  To use this common SPI logic on your board:

+ *

+ *   1. Provide stm32_spi1/2select() and stm32_spi1/2status() functions in your

+ *      board-specific logic.  This function will perform chip selection and

+ *      status operations using GPIOs in the way your board is configured.

+ *   2. Add a call to up_spiinitialize() in your low level initialization

+ *      logic

+ *   3. 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).
