[U-Boot] USB OTG host mode support in u-boot (Ethernet Over USB)

I am trying to get usb-ethernet dongle to work in u-boot but in order to get this to work I need to have the device in host mode. My current platform doesn't have USB host EHCI port but it has the micro OTG port and I have verified that keyboard/mouse/usb-ethernet all work on this port in Linux. But I have not been able to get ethernet over USB to work in u-boot (using Micro-A cable).

Ethernet over USB is already supported in u-boot for the USB host but it seems that USB OTG support is missing from u-boot. Can someone advise or suggest a solution to get ethernet over USB to work in u-boot using USB OTG host?

Thanks, Behnam
