Hi Julien,


Apologies for the delay.
It is okay. I myself was busy a bit.

As all TODOs and potential security issues are resolved now,
remove experimental status from OP-TEE mediator.

Looking at SUPPORT.MD, I think OP-TEE without this series would be
considered as "Experimental".

With this series applied, I still think we should keep the Kconfig
behind EXPERT but mark it as "Technical Preview" for at least a
release. This would encourage people to test and report any potential
issues with OP-TEE.

We can re-discuss about the state in a few months for future release.

BTW, SUPPORT.MD should be updated to reflect the state of OP-TEE in Xen.
Fair enough. In the next version I'll replace this patch with patch to
SUPPORT.md. Or it is better to push separate patch for the documentation?

I think the patch in SUPPORT.MD should go regardless of the state of
the rest. It is fine to keep it in this series.
Okay. By the way, I skimmed thru SUPPORT.MD and I'm not sure what is the
best place to describe mediator. So I could use some advice there.

Good question. I would put it under "## Virtual Hardware, Hypervisor". Maybe after the subsection "### ARM: Guest ACPI support"?
