Detailed Description

This file includes a standard driver for the N25Q256A QSPI memory mounted on STM32469I-EVAL board.

  ==============================================================================
                     ##### How to use this driver #####
  ==============================================================================  
  [..]
   (#) This driver is used to drive the S25FL512SAGMFI01 and N25Q512A QSPI external 
       memory mounted on STM32469I-EVAL evaluation board.
       
   (#) This driver need a specific component driver (FL512SAGMFI01 and N25Q512A) 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)
