Detailed Description

NAND Controller functions. 

 ===============================================================================
                    ##### NAND Controller functions #####
 ===============================================================================  

 [..]  The following sequence should be followed to configure the FMC to interface 
       with 8-bit or 16-bit NAND memory connected to the NAND Bank:
 
  (#) Enable the clock for the FMC and associated GPIOs using the following functions:
      (++)  RCC_AHB3PeriphClockCmd(RCC_AHB3Periph_FMC, ENABLE);
      (++)  RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOx, ENABLE);

  (#) FMC pins configuration 
      (++) Connect the involved FMC pins to AF12 using the following function 
           GPIO_PinAFConfig(GPIOx, GPIO_PinSourcex, GPIO_AF_FMC); 
      (++) Configure these FMC pins in alternate function mode by calling the function
           GPIO_Init();    
       
  (#) Declare a FMC_NANDInitTypeDef structure, for example:
      FMC_NANDInitTypeDef  FMC_NANDInitStructure;
      and fill the FMC_NANDInitStructure variable with the allowed values of
      the structure member.
      
  (#) Initialize the NAND Controller by calling the function
      FMC_NANDInit(&FMC_NANDInitStructure); 

  (#) Then enable the NAND Bank, for example:
      FMC_NANDCmd(FMC_Bank3_NAND, ENABLE);  

  (#) At this stage you can read/write from/to the memory connected to the NAND Bank. 
   
 [..]
  (@) To enable the Error Correction Code (ECC), you have to use the function
      FMC_NANDECCCmd(FMC_Bank3_NAND, ENABLE);  
 [..]
  (@) and to get the current ECC value you have to use the function
      ECCval = FMC_GetECC(FMC_Bank3_NAND);
