Detailed Description

This file includes a standard driver for the MT25TL01G QSPI memory mounted on STM32H747I-EVAL board.

Author: MCD Application Team

How To use this driver:
-----------------------
 - This driver is used to drive the MT25TL01G QSPI external
     memory mounted on STM32H747I-EVAL evaluation board.

 - This driver need a specific component driver (MT25TL01G) to be included with.

Driver description:
-------------------
 - 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.
       STR and DTR transfer rates are supported.
       SPI, SPI 2-IO, SPI-4IO and QPI modes are supported

 - 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_EraseBlock() and by
          specifying the block address. You can perform an erase operation of the whole
          chip by calling the function BSP_QSPI_EraseChip().
     + The function BSP_QSPI_GetStatus() returns the current status of the QSPI memory.
          (see the QSPI memory data sheet)
     + The function BSP_QSPI_EnableMemoryMappedMode enables the QSPI memory mapped mode
     + The function BSP_QSPI_DisableMemoryMappedMode disables the QSPI memory mapped mode
     + The function BSP_QSPI_ConfigFlash() allow to configure the QSPI mode and transfer rate

Note:
--------
  Regarding the "Instance" parameter, needed for all functions, it is used to select
  an QSPI instance. On the STM32H747I_EVAL board, there's one instance. Then, this
  parameter should be 0.
