Was it not possible to:

- emulate a standard 8250 UART and just expose an additional bar + MSI
vector such that one could get a debug UART out of this device with
little to no work on the host side?

- or use virtio console and implement virtio on the firmware that runs
on VK?

It's not a lot of code, but it just feels like this should not have to
be done at all.
