MIPS: Add support for the M5150 processor
The M5150 core is a 32-bit MIPS RISC which implements the MIPS Architecture Release-5 in a 5-stage pipeline. In addition, it includes the MIPS Architecture Virtualization Module that enables virtualization of operating systems, which provides a scalable, trusted, and secure execution environment.
