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).
