  ==============================================================================
                     ##### How to use this driver #####
  ==============================================================================
  [..]
   (#) This driver is used to drive the N25Q128A QSPI external
       memory mounted on STM32469I-Discovery board.

   (#) This driver need a specific component driver N25Q128A 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)
