IHMO, XSM should only be used to restrict usage of calls in a fine
grain. For an overall control, that should be go through a DOMCTL tell
Xen to initialize OP-TEE for that domain.
Just to be sure. You are proposing to add flag "TEE_ENABLED" for a
domain and set it during domain construction, based on configuration, right?
What did you mean by "fine grain"?
