These are the kernels with the dwc2 enabled (replaced dwc_otg with dwc2 for both arm64 and armhf kernels).

I just tested arm64 and armhf kernels on the rpi4 boards, the uart/ethernet/sd card/sound/hdmi display/wifi/usb host all worked well.

I will test them on rpi2/3 boards, and compare the usb performance (by copying large size files). I didn't test usb performance on rpi4 since the usb host on rpi4 is xhci rather than dwc_otg/dwc2.
