[U-Boot] USB console support for Cypress

Hi,

If one wants to have support for usb console (instead of serial) for u-boot using a specific USB host controller like the Cypress 7C63xxx family what is the correct approach? Is usbtty.c I need to start looking into, with all the necessary chip specific changes that need to be added, or is it something else? My research so far shows that Cypress 7C63xxx family is not supported in u-boot but I would be happy if somebody proves me wrong.

Thank you

Anton
