From d556fcc101c4b0d57ac9742ab806a6bfed78eac1 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Mon, 20 Apr 2009 19:31:20 +0900 Subject: [PATCH] sh: pci: Flag the dreamcast BBA as IORESOURCE_PCI_FIXED. This isn't a real BAR, so prevent any attempts to move it, as we don't wish to encourage a bus luck by overzealous PCI initialization code.
