Easy enough to add. Should be a separate device with its own pci id
though. According to the linux source code there seem to be two
common ways to implement this: A single, large pci bar where all
uarts are mapped one after the other. Or one pci bar for each uart.
Now I need to figure which is easier to handle for windows guests ...
cheers,
Gerd
