The System Reset Controller (SRC) is responsible for the generation of
all the system reset signals and boot argument latching.
Its main functions are as follows,
- Deals with all global system reset sources from other modules,
and generates global system reset.
- Responsible for power gating of MIXs (Slices) and their memory
low power control.
