Unprivileged Guest OS

This guest OS is also allowed to read and write to the SCRATCH_SECURE_RSV109_SCRATCH_0 register. The request to read and write is sent to Hypervisor and Hypervisor in turn does not read or write to the physical scratch register. Here, Hypervisor emulates the read and write. Unprivileged guest OS can request Hypervisor to perform a system reset but Hypervisor ignores the request and does nothing.
