From 320e68da59353fe6ad51b81f6865c4b674ad66ea Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Fri, 29 Jan 2010 22:38:13 +0900 Subject: sh: support PCI domains. Newer SH parts are now commonly shipping with multiple controllers, so we wire up PCI domain support to deal with them. Shamelessly cloned from the MIPS implementation.
