+ * Name: stm32_spi1/2/3select and stm32_spi1/2/3status
+ *
+ * Description:
+ * The external functions, stm32_spi1/2/3select and stm32_spi1/2/3status 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 up_spiinitialize())
+ * 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_spi1/2/3select() and stm32_spi1/2/3status() 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).
