How ARM Systems are Booted - An Introduction to the ARM Boot Flow

Explore the intricacies of ARM system boot processes in this 37-minute conference talk by Rouven Czerwinski from Pengutronix e.K. Gain insights into the increasing complexity of ARM boot flows, particularly in 64-bit systems that rely on ARM Trusted Firmware (TF-A) for CPU power management, system suspend, and other SoC-specific functions. Follow the journey from the reset vector through various firmware stages to the Linux boot-up procedure. Delve into topics such as OP-TEE and services provided by TF-A, including PSCI and SCMI, to enhance your understanding of modern ARM system architecture and boot sequences.
