Handoff between secure firmware and non-secure Firmware via HOB lists

Heinrich Schuchardt

Currently the SBI specification defines how to hand device-trees from the SEE to the S-mode firmware.

In the context of Trusted Firmware A a document has been developed describing what a more generic handover structure may look like that will also encompass ACPI tables and additional information like TPM measurements.


As probably EDK II and U-Boot will adopt parsing this structure it would make sense to discuss if the same can be used in the RISC-V world too.
