The bootrom plays a major role in the boot process of any i.MX6 SoC. In case the NAND memory is the boot devices, this implies that the boot partition must be organized in order fulfill the bootrom requirements. Specifically, it contains:
*A 1MB area (named Flash Control Block, FCB) which, in turn, includes
**A data structure called NAND Control Block (NCB)
**Three addresses which indicate where are located
***The Discovered Bad Block Table (DBBT) which is the data structure used to manage the bad blocks of the NAND flash
***The first copy of the firmware to load
***The second (redundant) copy of the firmware to load
*The DBBT
*The first copy of the firmware
*The second copy of the firmware.

For more details about the bootrom e the NAND boot process, please refer to the ''System Boot'' chapter of the Reference Manual of the specific i.MX6 Application Processor.

The following section will describe how to burn the boot partition in practice.
