+ * @brief NAND HAL module driver.
+ * This file provides a generic firmware to drive NAND memories mounted
+ * as external device.
+ *
+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ This driver is a generic layered driver which contains a set of APIs used to
+ control NAND flash memories. It uses the FMC/FSMC layer functions to interface
+ with NAND devices. This driver is used as follows:
+
+ (+) NAND flash memory configuration sequence using the function HAL_NAND_Init()
+ with control and timing parameters for both common and attribute spaces.
+
+ (+) Read NAND flash memory maker and device IDs using the function
+ HAL_NAND_Read_ID(). The read information is stored in the NAND_ID_TypeDef
+ structure declared by the function caller.
+
+ (+) Access NAND flash memory by read/write operations using the functions
+ HAL_NAND_Read_Page_8b()/HAL_NAND_Read_SpareArea_8b(),
+ HAL_NAND_Write_Page_8b()/HAL_NAND_Write_SpareArea_8b(),
+ HAL_NAND_Read_Page_16b()/HAL_NAND_Read_SpareArea_16b(),
+ HAL_NAND_Write_Page_16b()/HAL_NAND_Write_SpareArea_16b()
+ to read/write page(s)/spare area(s). These functions use specific device
+ information (Block, page size..) predefined by the user in the HAL_NAND_Info_TypeDef
+ structure. The read/write address information is contained by the Nand_Address_Typedef
+ structure passed as parameter.
+
+ (+) Perform NAND flash Reset chip operation using the function HAL_NAND_Reset().
+
+ (+) Perform NAND flash erase block operation using the function HAL_NAND_Erase_Block().
+ The erase block address information is contained in the Nand_Address_Typedef
+ structure passed as parameter.
+
+ (+) Read the NAND flash status operation using the function HAL_NAND_Read_Status().
+
+ (+) You can also control the NAND device by calling the control APIs HAL_NAND_ECC_Enable()/
+ HAL_NAND_ECC_Disable() to respectively enable/disable the ECC code correction
+ feature or the function HAL_NAND_GetECC() to get the ECC correction code.
+
+ (+) You can monitor the NAND device HAL state by calling the function
+ HAL_NAND_GetState()
+
+ [..]
+ (@) This driver is a set of generic APIs which handle standard NAND flash operations.
+ If a NAND flash device contains different operations and/or implementations,
+ it should be implemented separately.
