From 3d0f8bc7517718a4846de6f538ad67a4f7f83239 Mon Sep 17 00:00:00 2001 From: Martyn Welch Date: Thu, 27 Aug 2009 17:00:40 +0100 Subject: [PATCH] Staging: vme: Update support for the Universe II VME driver This patch starts the reworking of the vme_ca91cx42.c for the VME core. The driver seems to have only supported the Universe II for a long time, I have no hardware to check to see if it would work on the Universe I. This patch is compile tested with minimal run-time testing. It enables basic support for slave and master windows and interrupts. The master windows have undergone basic run testing.
