Cover letter [PATCH v7 0/4] ARM SMC Calling Convention interface
Quoted 6 lines · Jens Wiklander

This patch set is based on the Generic TEE subsystem v6 patchset
(https://lwn.net/Articles/662495/) sent out a some time ago. By isolating the ARM SMC Calling Convention patches that are useful for other purposes than to support the Generic TEE subsystem some complexity is removed from that patch set.

Quoted 7 lines

This patch set adds a common interface to do an SMC or HVC following ARM SMC Calling Convention. The interface is implemented for both the arm and arm64 architectures and updates the PSCI driver to use this interface instead for firmware communication.

Kevins previous Tested-by tag isn't included as the changes in the config variables may affect some of the builds.

OK, I applied this on top of v4.4-rc6 and pushed it through another round of build[1] and boot[2] testing and things look fine.
