* Name: pic32mx_spiNselect, pic32mx_spiNstatus, and pic32mx_spiNcmddata
*
* 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 PIC32MX logic. To use
* this common SPI logic on your board:
*
* 1. Provide logic in pic32mx_boardinitialize() to configure SPI/SSP chip select
* pins.
* 2. Provide pic32mx_spiNselect() and pic32mx_spiNstatus() 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
* pic32mx_spiNcmddata() functions in your board-specific logic. These
* 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
