[U-Boot] "EHCI timed out on TD" on OpenRD Ultimate

[Alexei Ozhigov]

Hello!


I tried running latest U-Boot on OpenRD Ultimate, and USB support
appears to be broken:


Marvell>> usb reset

(Re)start USB...

USB:   Register 10011 NbrPorts 1

USB EHCI 1.00

scanning bus for devices... EHCI timed out on TD - token=0x80008c80

2 USB Device(s) found

       scanning bus for storage devices... 0 Storage Device(s) found


According to "git bisect" the patch which causes this behavior is
c2dd0d45540397704de9b13287417d21049d34c6 (armv7: integrate cache
maintenance support).
I tried increasing USB_TIMEOUT_MS as was suggested by Jason Cooper,
but that did not help.
