All Qualcomm SoCs starting from SM8650 provide access to the Qualcomm Trusted Execution Environment (QTEE) through the SMCInvoke interface, implemented by the QCOMTEE driver. QTEE runs in the Secure World domain on ARM64 CPUs and exposes secure services to Linux running in the Normal World domain.
This change enables the QCOMTEE driver as a module to support communication with QTEE.
QCOMTEE has been tested on a Qualcomm RB3Gen2 board by loading and executing a Trusted Application via tests hosted at github.com/qualcomm/minkipc.
