+Cannot boot from EFI image on aarch64
+
+I am unable to boot from a EFI disk image on aarch64 qemu.
+
+I have qemu built and installed from sources on a jetson-nano
+
+qemu-system-aarch64 -version
+QEMU emulator version 5.2.50 (v5.2.0-3234-gbdee969c0e)
+Copyright (c) 2003-2021 Fabrice Bellard and the QEMU Project developers
+
+KVM and and virtio are enabled in host kernel. 
+
+Now I want to boot a ChromiumOS image. I have the image downloaded from here:
+
+https://chromium.arnoldthebat.co.uk/?dir=daily
+
+The image looks fine:
+
+rreddy78@jetson-nano:~/Downloads$ fdisk -lu chromiumos_image.bin

+
+Now I try booting like this:
+
+qemu-system-aarch64 -M virt -m 2048 -smp 2 -cpu host -enable-kvm  \
+-device usb-ehci -device usb-kbd  -device usb-mouse -usb -serial stdio  \

+-netdev user,id=mynet   \
+-device virtio-net-device,netdev=mynet \
+-bios edk2-aarch64-code.fd -no-reboot

+But I am unable to boot.
