The function domcreate_bootloader_done may branch early to
domcreate_stream_done, in case some error occoured. Here srs->dcs will be
NULL, which leads to a crash.
It is unclear what the purpose of that backpointer is. Perhaps it can be
removed, and domcreate_stream_done could use CONTAINER_OF.

This header files describes protocol between OP-TEE and OP-TEE client
driver in Linux. They are needed for upcoming OP-TEE mediator, which
is added in the next patch.
Reason to add those headers in separate patch is to ease up review.
Those files were taken from linux tree

OP-TEE usually uses the same idea with command buffers (see
previous commit) to issue RPC requests. Problem is that initially
it has no buffer, where it can write request. So the first RPC
request it makes is special: it requests NW to allocate shared
buffer for other RPC
From: Volodymyr Babchuk
Some fast SMCCC calls to OP-TEE should be handled in a special way.
Capabilities exchange should be filtered out, so only caps
known to mediator are used. Also mediator disables static SHM
memory capability, because it can't share OP-TEE memory with a domain.
Only domain c

Hello all,
This is the 4th version of TEE mediator patch series. In the meantime
virtualization support were merged into OP-TEE mainline.
Last time our mail server changed order of messages in the mail thread.
I hope, this time it will send them in the right way. But, pl

If TEE support is enabled with "tee=native" option in xl.cfg,
then we need to inform guest about available TEE.
Currently only OP-TEE is supported, so we'll create DT
node in a way that is expected by optee driver in linux.

The main way to communicate with OP-TEE is to issue standard SMCCC
call. "Standard" is a SMCCC term and it means that call can be
interrupted and OP-TEE can return control to NW before completing
the call.
In contrast with fast calls, where arguments and return values
are

Add very basic OP-TEE mediator. It can probe for OP-TEE presence,
tell it about domain creation/destruction and forward all known
calls.
This is all what is needed for Dom0 to work with OP-TEE as long as
Dom0 shares 1:1 mapped pages with OP-TEE. Any attempt to call OP-TEE
From: Volodymyr Babchuk
This patch adds basic framework for TEE mediators. Guests can't talk
to TEE directly, we need some entity that will intercept request
and decide what to do with them. "TEE mediator" is a such entity.
This is how it works: user can build XEN with multiple TEE mediators

From: Volodymyr Babchuk
Shared memory is widely used by NW (Normal World) to communicate with
TAs (Trusted Applications) in OP-TEE. NW can share part of own memory
with TA or with OP-TEE core, by registering it in OP-TEE, or by
providing a temporal reference. Anyways, information about such memor

This enumeration controls TEE type for a domain. Currently there is
two possible options: either 'none' or 'native'.
'none' is the default value and it basically disables TEE support at
all.
'native' enables access to a "real" TEE installed on a platform.
It is possible
From: Volodymyr Babchuk
OP-TEE can issue multiple RPC requests. We are interested mostly in
request that asks NW to allocate/free shared memory for OP-TEE
needs, because mediator needs to do address translation in the same
way as it was done for shared buffers registered by NW.
OP-TEE can ask NW
