I've heard it's a Virtio console device in PCI space.
The below is from Ubuntu 20.10 Server for arm64. For Linux I've used a kernel command line of "console=hvc0 root=/dev/vda1" as suggested by one of the other folks who have built SimpleVM.app, and it does appear to map to the Virtio console and disk attached.
