* are provided by common LPC313X logic. To use this common SPI logic on your
* board:
*
* 1. Provide logic in lpc313x_boardinitialize() to configure SPI chip select
* pins.
* 2. Provide lpc313x_spiselect() and lpc313x_spistatus() 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).

* Name: lpc313x_spiselect and lpc313x_spistatus
*
* Description:
* The external functions, lpc313x_spiselect and lpc313x_spistatus 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 LPC313X logic. To use this common SPI logic on your
* board:
*
* 1. Provide logic in lpc313x_boardinitialize() to configure SPI chip select
* pins.
* 2. Provide lpc313x_spiselect() and lpc313x_spistatus() 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).
