==============================================================================
##### Flash Extension features #####
==============================================================================
[..] Comparing to other previous devices, the FLASH interface for STM32H7xx
devices contains the following additional features
(+) Capacity up to 2 Mbyte with dual bank architecture supporting read-while-write
capability (RWW)
(+) Dual bank memory organization
(+) PCROP protection for all banks
(+) Global readout protection (RDP)
(+) Write protection
(+) Secure access only protection
(+) Bank / register swapping
(+) Cyclic Redundancy Check (CRC)
##### How to use this driver #####
==============================================================================
[..] This driver provides functions to configure and program the FLASH memory
of all STM32H7xx devices. It includes
(#) FLASH Memory Erase functions:
(++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and
HAL_FLASH_Lock() functions
(++) Erase function: Sector erase, bank erase and dual-bank mass erase
(++) There are two modes of erase :
(+++) Polling Mode using HAL_FLASHEx_Erase()
(+++) Interrupt Mode using HAL_FLASHEx_Erase_IT()
(#) Option Bytes Programming functions: Use HAL_FLASHEx_OBProgram() to:
(++) Set/Reset the write protection per bank
(++) Set the Read protection Level
(++) Set the BOR level
(++) Program the user Option Bytes
(++) PCROP protection configuration and control per bank
(++) Secure area configuration and control per bank
(++) Core Boot address configuration
(++) TCM / AXI shared RAM configuration
(++) CPU Frequency Boost configuration
(#) FLASH Memory Lock and unlock per Bank: HAL_FLASHEx_Lock_Bank1(), HAL_FLASHEx_Unlock_Bank1(),
HAL_FLASHEx_Lock_Bank2() and HAL_FLASHEx_Unlock_Bank2() functions
(#) FLASH CRC computation function: Use HAL_FLASHEx_ComputeCRC() to:
(++) Enable CRC feature
(++) Program the desired burst size
(++) Define the user Flash Area on which the CRC has be computed
(++) Perform the CRC computation
(++) Disable CRC feature- Attention
