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

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.
