I am not sure if this is the problem, but with these patches applied and no
media attached QEMU fails to initialize the EFI sub-system. IOW running
qemu-system-aarch64 -bios u-boot.bin -machine virt,secure=off -cpu cortex-a53
-m 2G -nographic -no-acpi
=> efidebug boot dump
No EFI system partition
Error: Cannot initialize UEFI sub-system, r = 14
We should always start EFI, even if scanning for boot options fails.
