* add the target for the Firmware Update secure partition.
  The secure partition is larger than the other partitions because the FIP
  is a large file (~4MB) and needs to be stored entirely in a secure world
  buffer before it's written into the NV storage.
* memory map the NOR Flash address space
* increment MAX_XLAT_TABLES to accomodate the mapping of the NOR
  flash device.
