                     ##### How to use this driver #####
  ==============================================================================       
    [..]
      This driver is a generic layered driver which contains a set of APIs used to 
      control NOR flash memories. It uses the FMC layer functions to interface 
      with NOR devices. This driver is used as follows:
    
      (+) NOR flash memory configuration sequence using the function HAL_NOR_Init() 
          with control and timing parameters for both normal and extended mode.
            
      (+) Read NOR flash memory manufacturer code and device IDs using the function
          HAL_NOR_Read_ID(). The read information is stored in the NOR_ID_TypeDef 
          structure declared by the function caller. 
        
      (+) Access NOR flash memory by read/write data unit operations using the functions
          HAL_NOR_Read(), HAL_NOR_Program().
        
      (+) Perform NOR flash erase block/chip operations using the functions 
          HAL_NOR_Erase_Block() and HAL_NOR_Erase_Chip().
        
      (+) Read the NOR flash CFI (common flash interface) IDs using the function
          HAL_NOR_Read_CFI(). The read information is stored in the NOR_CFI_TypeDef
          structure declared by the function caller.
        
      (+) You can also control the NOR device by calling the control APIs HAL_NOR_WriteOperation_Enable()/
          HAL_NOR_WriteOperation_Disable() to respectively enable/disable the NOR write operation  
       
      (+) You can monitor the NOR device HAL state by calling the function
          HAL_NOR_GetState() 
    [..]
     (@) This driver is a set of generic APIs which handle standard NOR flash operations.
         If a NOR flash device contains different operations and/or implementations, 
         it should be implemented separately.
