II. NAND partition table
All the board support boot from NAND flash will use the following NAND
partition table
0x00000000 - 0x0003FFFF bootstrap (256 KiB)
0x00040000 - 0x000BFFFF u-boot (512 KiB)

0x00200000 - 0x007FFFFF kernel (6 MiB)

III. Watchdog support
For security reasons, the at91 watchdog is running at boot time and,
if deactivated, cannot be used anymore.
