  * @brief   SRAM HAL module driver.

  *          mounted as external device.

  ==============================================================================
                          ##### How to use this driver #####
  ==============================================================================  
  [..]
    This driver is a generic layered driver which contains a set of APIs used to 
    control SRAM memories. It uses the FMC layer functions to interface 
    with SRAM devices.  
    The following sequence should be followed to configure the FMC/FSMC to interface
    with SRAM/PSRAM memories: 
      
   (#) Declare a SRAM_HandleTypeDef handle structure, for example:
          SRAM_HandleTypeDef  hsram; and: 
          
       (++) Fill the SRAM_HandleTypeDef handle "Init" field with the allowed 
            values of the structure member.
            
       (++) Fill the SRAM_HandleTypeDef handle "Instance" field with a predefined 
            base register instance for NOR or SRAM device 
                         
       (++) Fill the SRAM_HandleTypeDef handle "Extended" field with a predefined
            base register instance for NOR or SRAM extended mode 
             
   (#) Declare two FMC_NORSRAM_TimingTypeDef structures, for both normal and extended 
       mode timings; for example:
          FMC_NORSRAM_TimingTypeDef  Timing and FMC_NORSRAM_TimingTypeDef  ExTiming;
      and fill its fields with the allowed values of the structure member.
      
   (#) Initialize the SRAM Controller by calling the function HAL_SRAM_Init(). This function
       performs the following sequence:
          
       (##) MSP hardware layer configuration using the function HAL_SRAM_MspInit()
       (##) Control register configuration using the FMC NORSRAM interface function 
            FMC_NORSRAM_Init()
       (##) Timing register configuration using the FMC NORSRAM interface function 
            FMC_NORSRAM_Timing_Init()
       (##) Extended mode Timing register configuration using the FMC NORSRAM interface function 
            FMC_NORSRAM_Extended_Timing_Init()
       (##) Enable the SRAM device using the macro __FMC_NORSRAM_ENABLE()    

   (#) At this stage you can perform read/write accesses from/to the memory connected 
       to the NOR/SRAM Bank. You can perform either polling or DMA transfer using the
       following APIs:
       (++) HAL_SRAM_Read()/HAL_SRAM_Write() for polling read/write access
       (++) HAL_SRAM_Read_DMA()/HAL_SRAM_Write_DMA() for DMA read/write transfer
       
   (#) You can also control the SRAM device by calling the control APIs HAL_SRAM_WriteOperation_Enable()/
       HAL_SRAM_WriteOperation_Disable() to respectively enable/disable the SRAM write operation  
       
   (#) You can continuously monitor the SRAM device HAL state by calling the function
       HAL_SRAM_GetState()
