* Description:
* The external functions, lpc17_ssp0/ssp1select and lpc17_ssp0/ssp1status
* 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 lpc17_sspinitialize())
* are provided by common LPC17xx logic. To use this common SPI logic on your
* board:
*
* 1. Provide logic in lpc17_boardinitialize() to configure SPI/SSP chip select
* pins.
* 2. Provide lpc17_ssp0/ssp1select() and lpc17_ssp0/ssp1status() 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 lpc17_sspinitialize() in your low level application
* initialization logic
* 4. The handle returned by lpc17_sspinitialize() 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).
