From d55a299efd74431e98c8a4f24cffd07c95d419d6 Mon Sep 17 00:00:00 2001
From: Henrik Rydberg <rydberg@euromail.se>
Date: Tue, 15 Mar 2011 12:47:54 +0100
Subject: Introduce check test framework

Add the check test framework, and add a simple test to check
point to point mappings.

The tests use the device files as input.
