TRP is a small test payload that implements Realm Monitor Management (RMM) functionalities. RMM runs in the Realm world (R-EL2) and manages the execution of Realm VMs and their interaction with the hypervisor in Normal world. TRP is used to test the interface between RMM and Normal world software, known as Realm Management Interface (RMI). Current functions includes returning RMM version and transitioning granules from Non-secure to Realm world and vice versa. More information about RMM can be found at: https://developer.arm.com/documentation/den0125/latest Signed-off-by: Zelalem Aweke <zelalem.aweke@arm.com> Change-Id: Ic7b9a1e1f3142ef6458d40150d0b4ba6bd723ea2
