I have the V2 patch series here, tested it, was going to send it today
.... then received a new revision of the hardware/firmware which hides
the PCI device and the UART is driven by the 8250 driver and requires me
to use 3318 as the baud ..... ***sigh***. I'm not sure what the right
thing is to do right now. I'm going to have a conversation with the
hardware manufacturer and the TWO firmware teams I'm working with.

If anyone has experience with this sort of mess and would like to offer
a recommended course of action, I'm all ears.
