+Subject: [PATCH] runqemu: add virtio block device
+
+Implement new QB_DRIVE_TYPE="/dev/vdb" which falls back
+to virtio block device emulated by qemu.
+That is needed to support following qemu command line:
+-drive id=disk0,file=%s,if=none,format=%s \
+  -device virtio-blk-device,drive=disk0'
+
+Real use case is arm64 emulation with qemu with atf+optee+uboot,
+so that uboot driver sees this disk and able to load from it.
