I'm not sure I understand exactly how UEFI boot works in conjunction
with U-Boot. Where does the FDT come from in that set up? Does U-Boot
already load it from somewhere and pass it to Linux via UEFI? Or does
U-Boot pass on its builtin FDT? If the latter, that's not something
that we currently support, so I'm not surprised that it doesn't work.
Given the error message before the crash, I think you might get a little
further if you copy the "timer" node from Linux's tegra186.dtsi to that
in U-Boot.
