From f5c122da543ebf98a5ccb3166768e38eea3120dd Mon Sep 17 00:00:00 2001 From: Kevin Hilman Date: Tue, 14 Apr 2009 07:04:16 -0500 Subject: davinci: add arch_ioremap() which uses existing static mappings Add arch-specific ioremap() which uses any existing static mappings in place of doing a new mapping. From now on, drivers should always use ioremap() instead of IO_ADDRESS(). In addition, remove the davinci_[read|write]* macros in favor of using ioremap.
