* Add TZASC as unimplemented device.
  - Allow bare metal application to access this (unimplemented) device
* Add CSU as unimplemented device.
  - Allow bare metal application to access this (unimplemented) device
* Add various memory segments
  - OCRAM
  - OCRAM EPDC
  - OCRAM PXP
  - OCRAM S
  - ROM
  - CAAM
