From 9f568e512f54b452a4c533b766b40ad2e64446bc Mon Sep 17 00:00:00 2001
From: Gareth Hughes <gareth@valinux.com>
Date: Wed, 1 Nov 2000 03:14:12 +0000
Subject: [PATCH] Added trivial CVA test for testing HW driver fastpaths, good
 for testing indexed vertex buffer implementations for instance.

Cleaned up Makefile to make building and adding more tests easier.
