/****************************************************************************
* Name: sam3u_spiselect, sam3u_spistatus, and sam3u_spicmddata
*
* Description:
* These external functions must be provided by board-specific logic. They
* are implementations of the select, status, and cmddata 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 SAM3U
* logic. To use this common SPI logic on your board:
*
* 1. Provide logic in sam3u_boardinitialize() to configure SPI chip select
* pins.
* 2. Provide sam3u_spiselect() and sam3u_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.
* 2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
* sam3u_spicmddata() functions in your board-specific logic. This
* function will perform cmd/data selection operations using GPIOs in
* the way your board is configured.
* 3. Add a call 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: sam3u_spi1/2/3select and sam3u_spi1/2/3status

*
* Description:
* The external functions, sam3u_spi1/2/3select and sam3u_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 SAM3U logic. To use this common SPI logic on your
* board:
* These external functions must be provided by board-specific logic. They
* are implementations of the select, status, and cmddata 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 SAM3U
* logic. To use this common SPI logic on your board:
*
* 1. Provide logic in sam3u_boardinitialize() to configure SPI chip select
* pins.
* 2. Provide sam3u_spi1/2/3select() and sam3u_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
* 2. Provide sam3u_spiselect() and sam3u_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.
* 2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
* sam3u_spicmddata() functions in your board-specific logic. This
* function will perform cmd/data selection operations using GPIOs in
* the way your board is configured.
* 3. Add a call 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
* SPI driver to higher level logic (e.g., calling
* mmcsd_spislotinitialize(), for example, will bind the SPI driver to
* the SPI MMC/SD driver).
