description:
|
|
The Secure Processor SubSystem (SPSS) is a dedicated subsystem for security.
|
|
It has its own CPU, memories, and cryptographic engine.
|
|
It shall provide cryptographic services to other subsystems.
|
|
The SPSS firmware is loaded by PIL driver.
|
|
The communication with SPSS is done via spcom driver, using glink.
|
|
This document defines the binding for a component that selects the SPSS firmware file, according to a dedicated fuse and the platform HW version.
