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

How ARM Systems are Booted: An Introduction to the ARM Boot Flow - Rouven Czerwinski, Pengutronix e.K.
Nowadays ARM system boot flows are becoming more and more complex. Especially 64-Bit systems rely on the ARM Trusted Firmware (TF-A) and the provided system services to implement CPU power management, system suspend and other SoC specific functions. This talk will give an overview on how an ARM system starts at the reset vector, boots up the different firmware parts and finally arrives within the linux boot-up procedure. We will also touch the topic of OP-TEE and the services provided by the TF-A, i.e. PSCI and SCMI.
