+  *          functionalities of the Flexible Memory Controller (FMC) peripheral memories:
+  *           + Initialization/de-initialization functions

+  ==============================================================================
+                        ##### FMC peripheral features #####
+  ==============================================================================
+  [..] The Flexible memory controller (FMC) includes three memory controllers:
+       (+) The NOR/PSRAM memory controller
+       (+) The NAND/PC Card memory controller
+       (+) The Synchronous DRAM (SDRAM) controller 
+       
+  [..] The FMC functional block makes the interface with synchronous and asynchronous static
+       memories, SDRAM memories, and 16-bit PC memory cards. 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 FMC performs
+       only one access at a time to an external device.
+       The main features of the FMC controller are the following:
+        (+) Interface with static-memory mapped devices including:
+           (++) Static random access memory (SRAM)
+           (++) Read-only memory (ROM)
+           (++) NOR Flash memory/OneNAND Flash memory
+           (++) PSRAM (4 memory banks)
+           (++) 16-bit PC Card compatible devices
+           (++) Two banks of NAND Flash memory with ECC hardware to check up to 8 Kbytes of
+                data
+        (+) Interface with synchronous DRAM (SDRAM) memories
+        (+) Independent Chip Select control for each memory bank
+        (+) Independent configuration for each memory bank
+
