NOR typically refers to the NOR flash chip the application processor boots from. The baseband also uses a NOR flash.
How to Access
This can be accessed using a patched iBoot or a kernel hack. It can possibly be dumped using /dev/kmem
Memory Map
hope I did this right heh
0x0: "2GMI" fourcc |

Hardware
- iPhone -- some CFI compliant parallel nor
- iPhone 3G -- 1MB SPI NOR flash
