19Introduction
20------------
21
22There is a strong trend in the industry to provide microcontrollers in systems
23to abstract various power, or other system management tasks, away from
24Application Processors (APs). The Power Control System Architecture (PCSA) [1]
25describes how systems can be built following this approach.
26
27The PCSA defines the concept of the System Control Processor (SCP), a dedicated
28processor that is used to abstract power and system management tasks away from
29application processors.
30
31Similar to the SCP, the Manageability Control Processor (MCP) follows the same
32approach with the goal of providing a management entry-point to the System on
33Chip (SoC) where manageability is required, such as on a SoC targeting servers.
34
35SCP-firmware provides a software reference implementation for the System Control
36Processor (SCP) and Manageability Control Processor (MCP) components found in
37several Arm Compute Sub-Systems.
38
39Functionality
40-------------
41
42- Initialization of the system to enable application core boot
43- Runtime services:
44    - Power domain management
45    - System power management
46    - Performance domain management (Dynamic Voltage and Frequency Scaling)
47    - Clock management
48    - Sensor management
49    - Reset domain management
50    - Voltage domain management
51- System Control and Management Interface (SCMI, platform-side)
