[PATCH v2 0/4] ARM SMC Calling Convention interface

[Jens Wiklander]

Hi,

This patch set is based on the Generic TEE subsystem v6 patchset
(https://lwn.net/Articles/662495/) sent out two weeks 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.

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.

v2:
* Added unwinding support in the assembly functions

Thanks,
Jens
