There is a device entry in puc(4) for it, but I'm not sure if we got the uart speeds working right with the Oxford Semi native PCIE uart that this device uses, the clocking is based on PCIE and is at a frequency that is very different to other puc(4) devices and doesn't fit well with the way we encode them. That said, I was able to get a similar chip working, just the serial ports ran at the wrong speed (iirc it was halved or doubled compared to the speed requested).. > Would utilize it for the main console. This is fiddly with puc(4) devices in general - you need to identify the base address with pcidump and feed it to 'machine comaddr' in boot.conf and hope it doesn't change (which it may do especially if you add/remove other devices).
