From 2eb2a4368273e123d2716a704c86f3130aa14c22 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Fri, 19 Jun 2009 16:00:00 +0900 Subject: sh: SH7786 SMP support. SH7786 is roughly identical to SH-X3 proto SMP, though there are only 2 CPUs. This just wraps in to the existing SH-X3 SMP code with some minor changes for SH7786, including wiring up the IPIs properly, enabling IRQ_PER_CPU, and so forth.
