* Name: avr_spiselect, avr_spitatus, and avr_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 LPC17xx logic. To use
* this common SPI logic on your board:
*
* 1. Provide logic in up_boardinitialize() to configure SPI chip select
* pins.
* 2. Provide avr_spiselect() and avr_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 the
* avr_spicmddata() function in your board-specific logic. This functions 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).
