Important: To prevent indeterminate
system behavior, reserved areas of memory must not be accessed by software or
hardware. Any area of the memory map that is not explicitly defined as a register
space or accessible memory is considered reserved.

15:0 | size | Contains the length (in bytes) of the region in the On-chip RAM for the warm boot CRC validation. If the length is 0, the Boot ROM won't perform CRC calculation and CRC check to avoid overhead caused by CRC validation. If the START + LENGTH exceeds the maximum offset into the On-chip RAM, the Boot ROM won't boot from the On-chip RAM. The length must be an integer multiple of 4. The Boot ROM code will clear the top 16 bits and the bottom 2 bits. |
