Anyone know of a decent/simple EHCI stack to port to FILO?
Sorry, no.
I'm working from the 2.6 kernel driver at the moment,
What about the early serial stuff? (Not debug port, but the other.)
Maybe there's some EHCI stuff there?
And can anyone, perhaps with an EPIA or EPIA-M, confirm that UHCI is working in FILO? I've tried disabling the EHCI device, but it still fails on vt8237.
All EHCI controllers also provide one UHCI or OHCI (I forget if there's a choice or if not, which it should be) per physical port in order to have backwards compatibility for 1.x-only devices.
So you should find UHCI controller devices when EHCI is enabled. And if you disable EHCI, the UHCI/OHCI controllers should be disabled too.
Try plugging a low- or full-speed device into the controller.
