From e9c58fc57b17bfa75c256fb4f45ce22de6626858 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Thu, 12 Nov 2009 16:36:26 +0900 Subject: sh: Use the generic I/O port base for slowdown. This fixes up the build and behaviour for various configurations. Namely the CONFIG_32BIT cases where legacy mappings do not exist, as well as the sh64 build.
