+  *          This file provides firmware functions to manage the following 
+  *          functionalities of the Flexible Static Memory Controller (FSMC) peripheral memories:
+  *           + Initialization/de-initialization functions

+  =============================================================================
+                        ##### FSMC peripheral features #####
+  =============================================================================
+    [..] The Flexible static memory controller (FSMC) includes following memory controllers:
+         (+) The NOR/PSRAM memory controller
+       
+    [..] The FSMC functional block makes the interface with synchronous and asynchronous static
+         memories and SDRAM memories. Its main purposes are:
+         (+) to translate AHB transactions into the appropriate external device protocol.
+         (+) to meet the access time requirements of the external memory devices.
+   
+    [..] All external memories share the addresses, data and control signals with the controller.
+         Each external device is accessed by means of a unique Chip Select. The FSMC performs
+         only one access at a time to an external device.
+         The main features of the FSMC controller are the following:
+          (+) Interface with static-memory mapped devices including:
+             (++) Static random access memory (SRAM).
+             (++) NOR Flash memory.
+             (++) PSRAM (4 memory banks).
+          (+) Independent Chip Select control for each memory bank.
+          (+) Independent configuration for each memory bank.          
+        
+  =============================================================================
+                   ##### How to use NORSRAM device driver #####
+  =============================================================================
+ 
+  [..] 
+    This driver contains a set of APIs to interface with the FSMC NORSRAM banks in order
+    to run the NORSRAM external devices.
+      
+    (+) FSMC NORSRAM bank reset using the function FSMC_NORSRAM_DeInit() 
+    (+) FSMC NORSRAM bank control configuration using the function FSMC_NORSRAM_Init()
+    (+) FSMC NORSRAM bank timing configuration using the function FSMC_NORSRAM_Timing_Init()
+    (+) FSMC NORSRAM bank extended timing configuration using the function 
+        FSMC_NORSRAM_Extended_Timing_Init()
+    (+) FSMC NORSRAM bank enable/disable write operation using the functions
+        FSMC_NORSRAM_WriteOperation_Enable()/FSMC_NORSRAM_WriteOperation_Disable()
