12description: |
13  The System Reset Controller (SRC) is responsible for the generation of
14  all the system reset signals and boot argument latching.
15
16  Its main functions are as follows,
17  - Deals with all global system reset sources from other modules,
18    and generates global system reset.
19  - Responsible for power gating of MIXs (Slices) and their memory
20    low power control.
