* @brief FSMC Low Layer HAL module driver.

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

@verbatim
==============================================================================
##### FSMC peripheral features #####
==============================================================================
[..] The Flexible memory controller (FSMC) includes following memory controllers:
(+) The NOR/PSRAM memory controller
(+) The NAND/PC Card memory controller
[..] The FSMC 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 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)
(++) 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
(+) Independent Chip Select control for each memory bank
(+) Independent configuration for each memory bank

##### How to use PCCARD device driver #####
==============================================================================
[..]
This driver contains a set of APIs to interface with the FSMC PCCARD bank in order
to run the PCCARD/compact flash external devices.
(+) FSMC PCCARD bank reset using the function FSMC_PCCARD_DeInit()
(+) FSMC PCCARD bank control configuration using the function FSMC_PCCARD_Init()
(+) FSMC PCCARD bank common space timing configuration using the function
FSMC_PCCARD_CommonSpace_Timing_Init()
(+) FSMC PCCARD bank attribute space timing configuration using the function
FSMC_PCCARD_AttributeSpace_Timing_Init()
(+) FSMC PCCARD bank IO space timing configuration using the function
FSMC_PCCARD_IOSpace_Timing_Init()
