Amirreza Zarrabi	0f7bfdcb7c	tee: qcom: add primordial object ... After booting, the kernel provides a static object known as the primordial object. This object is utilized by QTEE for native kernel services such as yield or privileged operations.

Amirreza Zarrabi	d6e290837e	tee: add Qualcomm TEE driver ... 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.
