Perfect!
Just to note for other people, I have tested this backported patch on
linux 5.4 on Espressobin v5 board with "old arm trusted firmware"
version 2017.03-armada-17.10 from http://espressobin.net/tech-spec/
And on 5.4 kernel finally usb 3.0 port started working!
(of course with new arm trusted firmware compiled from source code there
is no such issue, but Espressobin comes with burned above old firmware
version)
