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.
