This temporary release is based on the following commit: commit 83b4731bab0423e3f9ffccfb37a882090be2f44a Author: Tao Yuhong <yuhong.tao@intel.com> Date: Wed Apr 14 07:43:11 2021 -0400 Change 64-bit MMIO BAR window to 256G-512G DM maps 64-bit mmio BARs of vdev into 4G-5G, for post-launched VMs. At native platform, 64-bit MMIO BARs which have 39-bit address, are always mapped into 256G-512G address space. DM will change the address window of 64-bit vdev BARs of post-launched VMs to 256G-512G. That ask OVMF to do the same change, to boot from passthrough SATA/MVME disks, which have 64-bit MMIO BAR. Tracked-On: #5913 Signed-off-by: Peter Fang <peter.fang@intel.com>
