[Xen-devel] [PATCH v2 00/13] TEE mediator (and OP-TEE) support in XEN

[Volodymyr Babchuk <volodymyr_babchuk@xxxxxxxx>]

From: Volodymyr Babchuk <vlad.babchuk@xxxxxxxxx>

Hello all,

This is v2 of patch series for OP-TEE mediator support in XEN. Changes from v1:

 - Added domctl interface, so now xl decides what domain should work with TEE
 - Removed XSM support due to change described above
 - Patch with OP-TEE mediator was splited to 7 separate patches
 - Removed patch with call_smccc() function. Now this series depend on
   Julien Grall's series "xen/arm: SMCCC fixup and improvement" [3]

=====
v1:

This is follow for patch series [1]. There was lots of discussions
for that series and I tried to address all of them in this new patchset.

Currently, I had a working solution for OP-TEE virtualization and it is being
upstreamed right now ([2]). So, I think it is a good time to introduce support
in XEN as well.

This series include generic TEE mediator framework and full-scale OP-TEE 
mediator
which is working with mentioned chages in OP-TEE. So, multiple domains can
work simultaneously with OP-TEE.

I added XSM support, so now it is possible to control which domains can work
with TEEs. Also I changed way how TEE discovery is done. Now  it is very
generic and should support any platform.
