Anyone using QE UART mode?

[Ying Lin]

OK, the missing piece (UART driver) I am looking for is not available
yet.  I will seek alternative solutions (create a simple UART driver, or
just wait).
Thanks for the information.

I'm working on a device driver for QE UART mode, but it's not working
yet.  The QE UART is 
like the CPM UART, but I'm having troubel getting it to work.

It is *not* trivial, or even easy, to enabled.  It's a full-blown UART
driver that also 
deals with the complexity of the QE.
