* The external functions, stm32_spi1/2/3select and stm32_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 |

||||
* are provided by common STM32 logic. To use this common SPI logic on your |
||||
* board: |
||||
* |
||||
* 1. Provide logic in stm32_boardinitialize() to configure SPI chip select |
||||
* pins. |
||||
* 2. Provide stm32_spi1/2/3select() and stm32_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 |
||||
* 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). |
