  How To use this driver:
  -----------------------
   - This driver is used to drive the IS61WV102416BLL-10M SRAM external memory mounted
     on STM32H743I-EVAL evaluation board.
   - This driver does not need a specific component driver for the SRAM device
     to be included with.

  Driver description:
  ------------------
  + Initialization steps:
     o Initialize the SRAM external memory using the BSP_SRAM_Init() function. This
       function includes the MSP layer hardware resources initialization and the
       FMC controller configuration to interface with the external SRAM memory.

  + SRAM read/write operations
     o SRAM external memory can be accessed with read/write operations once it is
       initialized.
       Read/write operation can be performed with AHB access using the functions
       BSP_SRAM_ReadData()/BSP_SRAM_WriteData(), or by DMA transfer using the functions
       BSP_SRAM_ReadData_DMA()/BSP_SRAM_WriteData_DMA().
     o The AHB access is performed with 16-bit width transaction, the DMA transfer
       configuration is fixed at single (no burst) halfword transfer
       (see the SRAM_MspInit() static function).
     o User can implement his own functions for read/write access with his desired
       configurations.
     o If interrupt mode is used for DMA transfer, the function BSP_SRAM_MDMA_IRQHandler()
       is called in IRQ handler file, to serve the generated interrupt once the DMA
       transfer is complete.
