Detailed Description

NOR/SRAM Controller functions.

 ===============================================================================
                    ##### NOR and SRAM Controller functions #####
 ===============================================================================  

 [..] The following sequence should be followed to configure the FSMC to interface
      with SRAM, PSRAM, NOR or OneNAND memory connected to the NOR/SRAM Bank:
 
   (#) Enable the clock for the FSMC and associated GPIOs using the following functions:
          RCC_AHB3PeriphClockCmd(RCC_AHB3Periph_FSMC, ENABLE);
          RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOx, ENABLE);

   (#) FSMC pins configuration 
       (++) Connect the involved FSMC pins to AF12 using the following function 
            GPIO_PinAFConfig(GPIOx, GPIO_PinSourcex, GPIO_AF_FSMC); 
       (++) Configure these FSMC pins in alternate function mode by calling the function
            GPIO_Init();    
       
   (#) Declare a FSMC_NORSRAMInitTypeDef structure, for example:
          FSMC_NORSRAMInitTypeDef  FSMC_NORSRAMInitStructure;
      and fill the FSMC_NORSRAMInitStructure variable with the allowed values of
      the structure member.
      
   (#) Initialize the NOR/SRAM Controller by calling the function
          FSMC_NORSRAMInit(&FSMC_NORSRAMInitStructure); 

   (#) Then enable the NOR/SRAM Bank, for example:
          FSMC_NORSRAMCmd(FSMC_Bank1_NORSRAM2, ENABLE);  

   (#) At this stage you can read/write from/to the memory connected to the NOR/SRAM Bank.
