* The external functions, lm3s_spiselect and lm3s_spistatus must be provided
* by board-specific logic. The are implementations of the select and status
* methods SPI interface defined by struct spi_ops_s (see include/nuttx/spi.h).
* All othermethods (including up_spiinitialize()) are provided by common
* logic. To use this common SPI logic on your board:
*
* 1. Provide lm3s_spiselect() and lm3s_spistatus() functions in your
* board-specific logic. This function will perform chip selection and
* status operations using GPIOs in the way your board is configured.
* 2. Add a call to up_spiinitialize() in your low level initialization
* logic
* 3. 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).
