In linux-based flash memory system is the use of the MTD (memory technology device) class device drivers implemented, MTD is linux-based device for accessing a flash memory (ROM, FLASH) drive subsystems. Its main purpose is to make the device easier to type Flash memory is accessed, for which it provides an abstract interface makes operation as hard as we can operate this type of equipment in hardware and operating systems in the upper. Carefully observed linux boot information friends see the following paragraph.

Because embedded Flash capacity is small, there is no need to adjust, so the partitions are fixed, and thus do not need to "partition table" in this computer
