  * @brief   This file includes the uSD card driver mounted on STM32H7B3I_EVAL
  *          boards.
  @verbatim
  How To use this driver:
  -----------------------
   - This driver is used to drive the micro SD external cards mounted on STM32H7B3I_EVAL
     board.
   - This driver does not need a specific component driver for the micro SD device
     to be included with.

  Driver description:
  ------------------
  + Initialization steps:
     o Initialize the micro SD card using the BSP_SD_Init() function. This
       function includes the MSP layer hardware resources initialization and the
       SDIO interface configuration to interface with the external micro SD. It
       also includes the micro SD initialization sequence for instance 0 or 1.

     o To check the SD card presence you can use the function BSP_SD_IsDetected() which
       returns the detection status for instance 0 or 1.

     o If SD presence detection interrupt mode is desired, you must configure the
       SD detection interrupt mode by calling the function BSP_SD_DetectITConfig().
       The interrupt is generated as an external interrupt whenever the micro SD card is
       plugged/unplugged in/from the evaluation board.
     The SD detection interrupt is handled by calling the function BSP_SD_DetectIT()
       which is called in the IRQ handler file, the user callback is implemented in
     the function BSP_SD_DetectCallback().

     o The function BSP_SD_GetCardInfo()are used to get the micro SD card information
       which is stored in the structure "HAL_SD_CardInfoTypedef".

  + Micro SD card operations
     o The micro SD card can be accessed with read/write block(s) operations once
       it is ready for access. The access can be performed whether
       using the polling mode by calling the functions BSP_SD_ReadBlocks()/BSP_SD_WriteBlocks(),
       using the interrupt mode by calling the functions BSP_SD_ReadBlocks_IT()/BSP_SD_WriteBlocks_IT(),
       or by DMA transfer using the functions BSP_SD_ReadBlocks_DMA()/BSP_SD_WriteBlocks_DMA().
       The access can be performed to instance 0 or 1.
     o The DMA transfer complete is used with interrupt mode. Once the SD transfer
       is complete, the SD interrupt is handled using the function BSP_SDMMC1_IRQHandler()
       when instance 0 is used or BSP_SDMMC2_IRQHandler() when instance 1 is used.
       The DMA Tx/Rx transfer complete are handled using the functions
       SD_SDMMC1_DMA_Tx_IRQHandler(), SD_SDMMC1_DMA_Rx_IRQHandler(),
       SD_SDMMC2_DMA_Tx_IRQHandler(), SD_SDMMC2_DMA_Rx_IRQHandler(). The corresponding
       user callbacks are implemented by the user at application level.
     o The SD erase block(s) is performed using the functions BSP_SD_Erase() with specifying
       the number of blocks to erase.
     o The SD runtime status is returned when calling the function BSP_SD_GetCardState().
