From 452976b29864f9adcdd6d4ea81001aa5483592c2 Mon Sep 17 00:00:00 2001 From: Haavard Skinnemoen <hskinnemoen@atmel.com> Date: Tue, 24 Oct 2006 10:12:45 +0200 Subject: [PATCH] AVR32: Use __raw MMIO access for internal peripherals The read[bwl] and write[bwl] functions are meant for accessing PCI devices. How this is achieved on AVR32 is unknown, as there are no systems with a PCI bridge available yet. On-chip peripheral access, however, should not depend on how we end up implementing PCI access, so using __raw_read[bwl]/__raw_write[bwl] is the right thing to do for on-chip peripherals. This patch converts the drivers for the static memory controller, interrupt controller, PIO controller and system manager to use __raw MMIO access.
