From a8f67f4b4d4b74cd14d3540ade8657ebee543340 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Mon, 26 Nov 2007 19:54:02 +0900 Subject: [PATCH] sh: Add SH7263 CPU support. This adds support for the SH7263 (SH-2A) CPU. This particular CPU is a superset of SH7203, adding some additional peripheral blocks and hooking up additional (reserved on SH7203) vectors in the INTC block. No visibly nasty surprises, yet..
