From a38de083d2979db3680f0d0978c509a172c8fa00 Mon Sep 17 00:00:00 2001 From: Olav Morken Date: Fri, 23 Jan 2009 12:56:28 +0100 Subject: AVR32: Move addrspace.h to arch-directory, and move some functions from io.h to addrspace.h The AVR32A architecture (which AT32UC3A-series is based on) has a different memory layout than the AVR32B-architecture. This patch moves addrspace.h to an arch-dependent directory in preparation for AT32UC3A-support. It also moves some address-space manipulation functions from io.h to addrspace.h.
