- * 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).
