The answer varies depending on your exact needs. If you are targeting
only on coreboot log obtainment, the RaspberryPI/BeagleBone with dwc2
is probably cheapest cross-platform thing to use. For kgdb, this setup
*should* work, but this would add another level of complexity due to
gdbserver spatial localization :) I`ve never tried working with
combination of the RPI and usb-ip to pass dwc2 port over cdc-ethernet
connection, this is the only major difference between 'real' dongle
and cheap board-based setup.
