Hi Kishon, Nice job! In my opinion, isolating dwc base drivers and cores in one dwc folder will improve code organization now and in the future. By creating pcie-designware-host and pcie-designware-endpoint cores will then add even more readbility. I think this is a good work base for your future developments. Thanks!
