From e8530033b8b5a353c884fd3c90457f703ff0bc38 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Sat, 14 Jun 2014 00:00:10 +0100 Subject: arch/mips: Add base MIPS architecture support Add the build infrastructure and basic architectural support required to build for targets using the MIPS architecture. This is sufficient to run on a simulator, but will require the addition of some cache maintenance and timer setup in order to run on real hardware.
