[U-Boot] Subject

[Eugeniu Rosca]

Hi Marek, Paul, cc: Alex

jFYI/FWIW, reverting [1-2] allows getting rid of below warnings on
R-Car3, when running basic fastboot commands (e.g. fastboot getvar):

[    8.035764] status: -104 ep 'ep1' trans: 0
[   18.744354] status: -104 ep 'ep1' trans: 28
[   18.748950] status: -104 ep 'ep1' trans: 9
[   18.753370] status: -104 ep 'ep1' trans: 28
[   26.064761] status: -104 ep 'ep1' trans: 28

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!
