No - again like the early serial stuff that's something that can be added once the base driver is mainlined if there's demand.
Does polling even work decently with the small fifo size of the uartlite?
I do not care about DCR, but as the responsible party for the only
board I am aware of that does use the uartlite as its
primary serial device, which typically does not have interrupt
support, that is something I care about alot.
You can poll a serial port on an 8080 running 1Mhz with a serial
port with no fifo.
16 bytes on a 300Mhz PPC is heaven. Works fine at 115K baud.

Ok. Patches are welcome.
