Flash Descriptor
The maximum size of the Flash Descriptor is 4 KB. If the block/sector size of the SPI 
Flash device is greater than 4 KB, the Flash Descriptor only uses the first 4 KB of the 
first block. The Flash Descriptor requires its own block at the bottom of memory (00h).
The information stored in the Flash Descriptor is only written during the board-level 
manufacturing process. The read/write permissions are set to read only when the 
system containing the SoC leaves the manufacturing floor.
The Flash Descriptor is made up of eleven sections as indicated in 
Figure 22-3. Flash Descriptor Sections
