I still don't understand the point of your driver. You're just
routing hcalls to a udbg back-end. So if you have a driver that
supports udbg but not standard console or TTY, then you can use your
driver to get console/tty I/O. Is there a platform where such a setup
exists? All HVC drivers support console and TTY, as do all serial
drivers. So what platform would use your driver?
