+ * @brief NOR HAL module driver.
+ * This file provides a generic firmware to drive NOR memories mounted
+ * as external device.
+ *
+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ This driver is a generic layered driver which contains a set of APIs used to
+ control NOR flash memories. It uses the FMC layer functions to interface
+ with NOR devices. This driver is used as follows:
+
+ (+) NOR flash memory configuration sequence using the function HAL_NOR_Init()
+ with control and timing parameters for both normal and extended mode.
+
+ (+) Read NOR flash memory manufacturer code and device IDs using the function
+ HAL_NOR_Read_ID(). The read information is stored in the NOR_ID_TypeDef
+ structure declared by the function caller.
+
+ (+) Access NOR flash memory by read/write data unit operations using the functions
+ HAL_NOR_Read(), HAL_NOR_Program().
+
+ (+) Perform NOR flash erase block/chip operations using the functions
+ HAL_NOR_Erase_Block() and HAL_NOR_Erase_Chip().
+
+ (+) Read the NOR flash CFI (common flash interface) IDs using the function
+ HAL_NOR_Read_CFI(). The read information is stored in the NOR_CFI_TypeDef
+ structure declared by the function caller.
+
+ (+) You can also control the NOR device by calling the control APIs HAL_NOR_WriteOperation_Enable()/
+ HAL_NOR_WriteOperation_Disable() to respectively enable/disable the NOR write operation
+
+ (+) You can monitor the NOR device HAL state by calling the function
+ HAL_NOR_GetState()
+ [..]
+ (@) This driver is a set of generic APIs which handle standard NOR flash operations.
+ If a NOR flash device contains different operations and/or implementations,
+ it should be implemented separately.
+
+ *** NOR HAL driver macros list ***
+ =============================================
+ [..]
+ Below the list of most used macros in NOR HAL driver.
+
+ (+) NOR_WRITE : NOR memory write data to specified address
+
+ *** Callback registration ***
+ =============================================
+ [..]
+ The compilation define USE_HAL_NOR_REGISTER_CALLBACKS when set to 1
+ allows the user to configure dynamically the driver callbacks.
+
+ Use Functions @ref HAL_NOR_RegisterCallback() to register a user callback,
+ it allows to register following callbacks:
+ (+) MspInitCallback : NOR MspInit.
+ (+) MspDeInitCallback : NOR MspDeInit.
+ This function takes as parameters the HAL peripheral handle, the Callback ID
+ and a pointer to the user callback function.
+
+ Use function @ref HAL_NOR_UnRegisterCallback() to reset a callback to the default
+ weak (surcharged) function. It allows to reset following callbacks:
+ (+) MspInitCallback : NOR MspInit.
+ (+) MspDeInitCallback : NOR MspDeInit.
+ This function) takes as parameters the HAL peripheral handle and the Callback ID.
+
+ By default, after the @ref HAL_NOR_Init and if the state is HAL_NOR_STATE_RESET
+ all callbacks are reset to the corresponding legacy weak (surcharged) functions.
+ Exception done for MspInit and MspDeInit callbacks that are respectively
+ reset to the legacy weak (surcharged) functions in the @ref HAL_NOR_Init
+ and @ref HAL_NOR_DeInit only when these callbacks are null (not registered beforehand).
+ If not, MspInit or MspDeInit are not null, the @ref HAL_NOR_Init and @ref HAL_NOR_DeInit
+ keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
+
+ Callbacks can be registered/unregistered in READY state only.
+ Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
+ in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
+ during the Init/DeInit.
+ In that case first register the MspInit/MspDeInit user callbacks
+ using @ref HAL_NOR_RegisterCallback before calling @ref HAL_NOR_DeInit
+ or @ref HAL_NOR_Init function.
+
+ When The compilation define USE_HAL_NOR_REGISTER_CALLBACKS is set to 0 or
+ not defined, the callback registering feature is not available
+ and weak (surcharged) callbacks are used.
