+ *         should accept zero/NULL as a default configuration.

+ * Name: stm32_spi1/2/select and stm32_spi1/2/status
+ *
+ * Description:
+ *   The external functions, stm32_spi1/2select and stm32_spi1/2status
+ *   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/spi.h).  All other methods (including
+ *   stm32_spibus_initialize()) are provided by common STM32 logic.  To use this
+ *   common SPI logic on your board:
+ *
+ *   1. Provide logic in stm32_boardinitialize() to configure SPI chip select
+ *      pins.
+ *   2. Provide stm32_spi1/2select() and stm32_spi1/2status() 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 stm32_spibus_initialize() in your low level application
+ *      initialization logic
+ *   4. The handle returned by stm32_spibus_initialize() 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).
