  14   The R-Car and RZ/G Reset Controllers provide reset control, and implement the
  15   following functions:
  16     - Latching of the levels on mode pins when PRESET# is negated,
  17     - Mode monitoring register,
  18     - Reset control of peripheral devices (on R-Car Gen1),
  19     - Watchdog timer (on R-Car Gen1),
  20     - Register-based reset control and boot address registers for the various
  21       CPU cores (on R-Car Gen2 and Gen3, and on RZ/G).
