   Follow the 6 steps below to configure flash memory for FAT
   
   Step 1. Modify the value of FLASH_BASE_ADDRESS, which is the starting address
           of the flash memory allocated for FAT

   Step 2. Modify the value of ALLOCATED_FAT_SPACE, which is the total flash
           space allocated for FAT
           
   Step 3. Modify the value of Block size 
           
   Step 4. Fill the flash bank (partition) information table,
           flash device features flexible, multi-bank read-while-program and 
           read-while-erase capability, enabling background programming or erasing in 
           one bank simultaneously with code execution or data reads in another bank.
           Each element in the table is the format as below:
           {bank size, bank number},   
                          
   Step 5. Modify the value of LSMT, you can see MemoryDevice_FlashDisk_FAQ for 
           detail information
      
   Step 6: Define the toal sectors (512bytes) of system drive
           the remainder is the size of public drive
           If there is no partiton (just one drive, system drive)
           set this value to STORAGE_NO_PARTITION (0xFFFFFFFF) 
 
           
   Note : Code region and FAT region can not share the same bank (partition)
