Yes, there is support for that in edk2.
Build:
$ git submodule update --init --force
$ . edksetup.sh
$ nice make -C "$EDK_TOOLS_PATH" -j $(getconf _NPROCESSORS_ONLN)
$ build -a ARM -b DEBUG -p ArmVirtPkg/ArmVirtQemu.dsc -t GCC5
$ for FD in QEMU_EFI.fd QEMU_VARS.fd; do
cat -- \
"$WORKSPACE/Build/ArmVirtQemu-ARM/DEBUG_GCC5/FV/$FD" \
/dev/zero \
| head -c 64m >| /tmp/"$FD.padded"
done
Run:
$ if ! [ -e vars.fd ]; then
cp /tmp/QEMU_VARS.fd.padded vars.fd
fi
$ qemu-system-arm \
-M virt \
-cpu cortex-a15 \
-m 1024 \
-serial stdio \
-drive
if=pflash,unit=0,format=raw,readonly=on,file=/tmp/QEMU_EFI.fd.padded \
-drive if=pflash,unit=1,format=raw,file=vars.fd \
-device virtio-gpu-pci \
-device id=xhci0,driver=qemu-xhci \
-device usb-kbd,bus=xhci0.0 \
-boot menu=on,splash-time=5000 \
