Great to know this.

Do we need to use qemu for virtio backend?

Alice in Cc is doing this effort together with i.MX8QM upstreaming.

Yeah!! Besides this, any people still interested in booting jailhouse before Linux? I have achieved this on i.MX8MM with Linux + gic-demo cell, with a baremetal program and using U-Boot FIT to load all images.
