Import FreeBSD/arm kernel bits. It only supports sa1110 (on simics) right now, but xscale support should come soon. Some of the initial work has been provided by : Stephane Potvin <sepotvin at videotron.ca> Most of this comes from NetBSD. 2004-05-14 11:46:45 +00:00			`/* $NetBSD: trap.h,v 1.1 2001/02/23 03:48:19 ichiro Exp $ */`
