[U-Boot] [U-BOOT] error: end address not on sector boundary when I use saveenv cmd

[Penda, Naveen Kumar]

Hi Rubini 

  I already looked at my  config file, but couldn't root cause the problem
  Here are some of the definitions from my configs, incase anything wrong 
  Can you please help me.

   NOR Flash:
     CONFIG_SYS_FLASH_BASE  0x10000000
     CONFIG_ENV_ADDR        0x10040000 
     CONFIG_SYS_MAX_FLASH_SECT 512 // Maximum number sectors
     CONFIG_SYS_MAX_FLASH_BANKS 1   
     CONFIG_SYS_MONITOR_LEN SZ_256K   
                NOR_SIZE   SZ_128M   //128MB NOR
                SECTOR_SIZE SZ_256K  // 256KB sector size
