Any interest in dwc-otg (aka dwc2) device emulation? For Raspi 3 and below.

[Paul Zimmerman]

Hi Folks,

I have been working on an emulation of the dwc-otg USB controller
(host mode only for now), as implemented on the Raspberry Pi 3 and
below, and on numerous other embedded platforms. I have it to a point
where it works pretty well with the dwc2 driver in the mainline Linux
kernel, and with the dwc-otg driver in the Raspbian kernel. Mouse and
keyboard work fine, and I *think* the usb-net device is working too,
although I have been unsuccessful in connecting to the outside world
with it.

I haven't done anything with gadget-mode yet, but that could certainly
be added in the future.

Would there be any interest in me submitting this for inclusion in
Qemu? I ask because I see there was a previous effort at this at
github.com/0xabu/qemu/hw/usb/bcm2835_usb.c, but it seems it never went
anywhere.

Thanks,
Paul
