From 9bb019f4c25a426deab26c9d1c67c8914bb4424f Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Mon, 6 Apr 2009 11:37:15 +0000 Subject: [PATCH] sh: sh7785lcr: fix PCI address map for 32-bit mode Fix the problem that cannot work PCI device on 32-bit mode because influence of the commit 68b42d1b548be1840aff7122fdebeb804daf0fa3 ("sh: sh7785lcr: Map whole PCI address space."). So this patch was implement like a 29-bit mode, map whole physical address space of DDR-SDRAM.
