Is this still needed? In my old p3450 branch that I worked on to get
Porg up and running I don't have this patch. It's also not in my local
development tree that I typically use to boot Tegra186 and earlier
boards. That branch works fine on the Jetson Nano, so I don't think this
is needed anymore. I vaguely recall that I determined that this was
fixed some other way, but unfortunately I don't remember the exact
details.
