I don't know of an ehci-ppc4xx.c file. Did you create it yourself?
I created the file by myself. But it's nothing more than setting up register base addresses similar with ehci-ixp4xx.c ...
I checked out from current source a few days ago. Maybe it's not very straight forward to get ppc4xx support working (as I originally thought). I'll take a look later this week.
thanks,
Chris

EHCI is currently not supported in U-Boot for PPC4xx.
I'm getting the following message when issuing "usb start" .
Cannot enable port 1 after 5 retries, disabling port.
Maybe the USB cable is bad?
Cannot reset port 1!?

EHCI works fine under operating system (a customized NetBSD). This is the configuration I'm using,
.
#define CONFIG_USB_EHCI
#define CONFIG_USB_EHCI_PPC4XX /* added ehci-ppc4xx.c similar as ehci-ixp4xx.c */
I don't know of an ehci-ppc4xx.c file. Did you create it yourself?
Cheers, Stefan
