==============================================================================
                   ##### How to use this driver #####
==============================================================================  
[..] 
 (#) This driver is used to drive the MX25L512 QSPI external
     memory mounted on STM32F769I-Discovery board.
     
 (#) This driver need a specific component driver (MX25L51245G) to be included with.

 (#) Initialization steps:
     (++) Initialize the QPSI external memory using the BSP_QSPI_Init() function. This 
          function includes the MSP layer hardware resources initialization and the
          QSPI interface with the external memory.

 (#) QSPI memory operations
     (++) QSPI 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_QSPI_Read()/BSP_QSPI_Write(). 
     (++) The function BSP_QSPI_GetInfo() returns the configuration of the QSPI memory. 
          (see the QSPI memory data sheet)
     (++) Perform erase block operation using the function BSP_QSPI_Erase_Block() and by
          specifying the block address. You can perform an erase operation of the whole 
          chip by calling the function BSP_QSPI_Erase_Chip(). 
     (++) The function BSP_QSPI_GetStatus() returns the current status of the QSPI memory. 
          (see the QSPI memory data sheet)
