* @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 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
