From 50b91449a3a073af3a7c87af83002016e7e34cc4 Mon Sep 17 00:00:00 2001 From: Laszlo Ersek Date: Thu, 24 Sep 2015 21:40:36 +0000 Subject: ArmVirtPkg: VirtFdtDxe: detect fw-cfg DMA interface from the DTB A DMA-like transfer interface has recently been implemented in QEMU for fw-cfg. For ARM and AARCH64 virtual machines, the binding prescribes a new 8-byte wide register at offset 0x10 in the register block. Make VirtFdtDxe expose this register if it is present. Please see "docs/specs/fw_cfg.txt" in the QEMU tree for more information.
