From f36c4720fca325579faddc880d4e178e4ccbda88 Mon Sep 17 00:00:00 2001 From: Leonid Yegoshin Date: Tue, 4 Mar 2014 13:34:43 +0000 Subject: [PATCH] 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.
