 ARM11 kernel virtual address mappings for these registers varies for different builds. For ARM11 user mode applications you have:
   physaddr = virtaddr - 0x1EC00000 + 0x10100000
-=0x10012000=
-Keys seem to be stored here? Access to this region is disabled once the ARM9 writes 0x2 to [[CONFIG|REG_SYSPROT9]].
-Originally the console-unique TWL keyinit + region disable was done by Kernel9. However, with the [[New_3DS]] FIRM ARM9 binary this is now done in the [[FIRM]] ARM9 binary loader, which also uses the 0x10012000 region for key generation.
-The first 0x100-bytes here are console-unique.

-| On development units ([[CONFIG|UNITINFO]]!=0) ARM9 uses the first 8-bytes from 0x10012000 for the TWL keydata. This doesn't seem to be used by NATIVE_FIRM on retail, besides New3DS key-generation in the [[FIRM|ARM9-loader]].
