+ * @version V1.1.0
+ * @date 16-September-2015
+ * @brief FMC Low Layer HAL module driver.
+ * This file provides firmware functions to manage the following
+ * functionalities of the Flexible Memory Controller (FMC) peripheral memories:
+ * + Initialization/de-initialization functions
+ * + Peripheral Control functions
+ * + Peripheral State functions
+ *
+ @verbatim
+ ==============================================================================
+ ##### FMC peripheral features #####
+ ==============================================================================
+ [..] The Flexible memory controller (FMC) includes following memory controllers:
+ (+) The NOR/PSRAM memory controller
+ (+) The NAND memory controller
+
+ [..] The FMC functional block makes the interface with synchronous and asynchronous static
+ 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).
+ (++) NOR Flash memory.
+ (++) PSRAM (4 memory banks).
+ (++) Two banks of NAND Flash memory with ECC hardware to check up to 8 Kbytes of
+ data
+ (+) Independent Chip Select control for each memory bank
+ (+) Independent configuration for each memory bank
