Thanks, that helped. FTR, I can boot it even without UEFI:

bin/qemu-system-aarch64 -M virt,accel=tcg -m 2048 -cpu cortex-a57 \
  -kernel ./vmlinuz-4.0.4-301.fc22.aarch64 \
  -initrd ./initramfs-4.0.4-301.fc22.aarch64.img \
  -append "console=ttyAMA0 root=/dev/sda4 ro" \
  -device virtio-scsi-device,id=scsi -device scsi-hd,drive=hd0 \
  -drive id=hd0,if=none,snapshot=on,file=./fedora-22.aarch64.img \
  -device virtio-net-device,netdev=usernet \
  -netdev user,id=usernet \
  -monitor stdio

... but UEFI is the reason I wanted to tinker with it in the first
place :)

Thanks much,
