- * Name:  kinetis_spi1/2/3select and kinetis_spi1/2/3status
- *
- * Description:
- *   The external functions, kinetis_spi1/2/3select and kinetis_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/spi.h). All other methods (including up_spiinitialize())
- *   are provided by common Kinetis logic.  To use this common SPI logic on your
- *   board:
- *
- *   1. Provide logic in kinetis_boardinitialize() to configure SPI chip select
- *      pins.
- *   2. Provide kinetis_spi1/2/3select() and kinetis_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).
