Detailed Description

This file includes the uSD card driver mounted on STM32H743I-EVAL evaluation boards.

  How To use this driver:
  -----------------------
   - This driver is used to drive the micro SD external cards mounted on STM32H743I-EVAL
     evaluation 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 SDCard1.
     o To check the SD card presence you can use the function BSP_SD_IsDetected() which
       returns the detection status for SDCard1. The function BSP_SD_IsDetected() returns
       the detection status for SDCard1.
     o If SD presence detection interrupt mode is desired, you must configure the
       SD detection interrupt mode by calling the functions BSP_SD_ITConfig() for
       SDCard1. The interrupt is generated as an external interrupt whenever the
       micro SD card is plugged/unplugged in/from the evaluation board. The SD detection
       is managed by MFX, so the SD detection interrupt has to be treated by MFX_IRQOUT
       gpio pin IRQ handler.
     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, by default to SDCard1, can be performed whether
       using the polling mode by calling the functions BSP_SD_ReadBlocks()/BSP_SD_WriteBlocks(),
       or by DMA transfer using the functions BSP_SD_ReadBlocks_DMA()/BSP_SD_WriteBlocks_DMA().
     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 SDCard1 is used.
     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_GetStatus().
