New SoCs often embed multiple heterogeneous processors. Buses, memories or peripherals managed by the SoC could be allocated to different processors. Shared system resources, such as clocks or power controllers, might be critical in the system and need to be controlled by a high level privileged and trusted entity. Whatever the hardware solution used, software drivers must remain agnostics. The talk will present the shared resources constraints and how the STM32MP1 explores and extends the ARM System Control and Management Interface as solution for such shared resources management.
Security developer in STMicroelectronics, focus on MPU projects (STM32MP1), I'm fully engaged in the software boot chain development (Trusted firmware/OP-TEE based) and security constraint for IOT.
