From ece77e4047c36ddd177949e81d548bda244ea8a7 Mon Sep 17 00:00:00 2001 From: Olivier Martin Date: Wed, 11 Dec 2013 16:58:39 +0000 Subject: OvmfPkg/Virtio: Removed VirtioReadDevice() / VirtIoWriteDevice() functions These functions did not provide much more than the new protocol functions VIRTIO_DEVICE_PROTOCOL.ReadDevice() / VIRTIO_DEVICE_PROTOCOL.WriteDevice().
