PI v1.5 Specification Volume 4 defines Management Mode Core Interface and defines EFI_MM_COMMUNICATION_PROTOCOL. This protocol provides a means of communicating between drivers outside of MM and MMI handlers inside of MM. This patch implements the EFI_MM_COMMUNICATION_PROTOCOL DXE runtime driver for AARCH64 platforms. It uses SMCs allocated from the standard SMC range defined in DEN0060A_ARM_MM_Interface_Specification.pdf to communicate with the standalone MM environment in the secure world. This patch also adds the MM Communication driver (.inf) file to define entry point for this driver and other compile related information the driver needs.
