Greetings,
I just got EHCI also :-)
I'm not sure it's all that necessary to support EHCI in firmware since any USB 2.0 device is required to fall back if necessary. EHCI devices are required to include a UHCI or OHCI companion device to handle 1.1 devices. There's a bitmask to select which controls each port.
The USB boot over 1.1 only takes a second or 2 for a Linux kernel. Given all that, the best bet is probably just set the ports to the companion controller and support OHCI and UHCI.
G'day, sjames

Dumb question - how much work is it to add OHCI?
Duh, sorry, meant EHCI. The USB 2.0 one.
