Hi,
jFYI/FWIW, reverting [1-2] allows getting rid of below warnings on R-Car3, when running basic fastboot commands (e.g. fastboot getvar):
Maybe a more constructive approach would be to send a patch fixing the issue instead of reverting patches :)

This has been pointed out by Dmytro (To:) in one of his patches which reached us via official Renesas release. Since R-Car USB gadget driver is not yet present in mainline [3], the behavior cannot be reproduced with vanilla U-Boot. In case, at some point in time, you hit the same problem and come to the same or an alternative solution, please share. TIA!
Since this is gadget code, CCing U-Boot USB gadget maintainer.
