SMCInvoke driver is a misc driver to support communication between secure and non-secure world, based on new capability based model. Earlier, QSEECom driver had several problems such as exposing many interfaces to accomplish various tasks on secure world side. Ideally, driver should work as transparent as possible and provide just tunnel to communicate between secure and non secure world. SMCInvoke driver aims to achieve that.
