I'm just curious - is it really have to be UART? can it be a PV TTY

provide "serial" function?
There is a couple of usecase where we cannot use PV console:
- Running unmodified baremetal application as guest. Those applications
will not have PV driver.
- Guest compliant with the VM system specification for ARM [1]. A pl011
is required.
Do you have any concern with this?
