From: "Yingshiuan Pan" <yingshiuan.pan@xxxxxxxxxxxx> GenieZone is MediaTek proprietary hypervisor solution, and it is running in EL2 stand alone as a type-I hypervisor. It is a pure EL2 implementation which implies it does not rely any specific host VM, and this behavior improves GenieZone's security as it limits its interface.
