From 15444a8973dcfbd286b3e638cbadac2446a9271a Mon Sep 17 00:00:00 2001 From: David McKay Date: Mon, 24 Aug 2009 16:10:40 +0900 Subject: sh: Allow use of GENERIC_IOMAP The synopsys PCI cell used in the later STMicro chips requires code to be run in order to do IO cycles, rather than just memory mapping the IO space. Rather than extending the existing SH infrastructure to allow this, use the GENERIC_IOMAP implmentation to save re-inventing the wheel. This set of changes allows the SH to be built with GENERIC_IOMAP enabled, it just ifdef's out the functions provided by the GENERIC_IOMAP implementation, and provides a few required missing functions.
