From 1a442fe02d205d6980202b07f799ab9336e72ad7 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Fri, 21 Sep 2007 19:16:05 +0900 Subject: sh: Initial SH-X3 SMP support. This adds basic support for SH-X3 SMP (4 CPUs). More IPI and cache debugging is necessary, mostly interfacing the d-cache coherency and the I-cache broadcast invalidates. Only for testing at present!
