Subject: [EXT] USB3 XHCI crashing with USB 3 hub on Octeon

I have a follow-up. USB is working on our OcteonTX boards running 2020.10. It 
may be something specific to the Octeon port. Note that I did see a problem 
where the scratchpad memory is using direct pointers instead of physical 
addresses (which will not work on MIPS). As far as I know, however, the Octeon 
XHCI controller does not use the scratchpad memory.
