From 6df26700c0884cb3cce2b9fa4795888f86ca4d8f Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Tue, 13 Feb 2007 17:11:04 +0100 Subject: [ARM] 4182/1: iop3xx: fix the ioremap implementation to not remap static ranges Implement a custom ioremap implementation for iop3xx. This saves establishing new mappings. It also cleans up the PCI IO resource to be a physical address rather than a virtual address as Russell pointed out on the original iop13xx port.
