Introduce qcomtee_object, which represents an object in both QTEE and the kernel. QTEE clients can invoke an instance of qcomtee_object to access QTEE services. If this invocation produces a new object in QTEE, an instance of qcomtee_object will be returned. Similarly, QTEE can request services from by issuing a callback request, which invokes an instance of qcomtee_object. Implement initial support for exporting qcomtee_object to userspace and QTEE, enabling the invocation of objects hosted in QTEE and userspace through the TEE subsystem.

This option enables the Qualcomm Trusted Execution Environment (QTEE)
|
|
driver. It provides an API to access services offered by QTEE and
|
|
its loaded Trusted Applications (TAs). Additionally, it facilitates
|
|
the export of userspace services provided by supplicants to QTEE.
