Hi all,

This is very basic implementation for in-kernel support for Arm FF-A
specification.

Arm Firmware Framework for Armv8-A specification[1] describes a software
architecture that provides mechanism to utilise the virtualization
extension to isolate software images and describes interfaces that
standardize communication between the various software images. This
includes communication between images in the Secure and Normal world.

The main idea here is to create FFA device to establish any communication
with a secure partition. This is currently tested with OPTEE(with changes
to OPTEE driver adding FFA as transport)

Since you reviewed the last version, it would be helpful if you provide
Reviewed-by or Tested-by if you happy with this version. I would like to
get this initial version merged for v5.13

I've tested this in a few of my setups and everything looks over all
fine, so please apply:
Tested-by: Jens Wiklander <jens.wiklander@linaro.org>

I'm also double checking the details of the patches for some further
feedback. Stay tuned.

Thanks,
Jens
