I just uploaded a new cyrus_p5020.dtb file to
people.freebsd.org/~jhibbits, so go ahead and try that one, it's the
one I use on my machine.

The crash above is in U-Boot context, so likely still in loader.  Trap
800 is FPU unavailable, so make sure your kernel is sane, as you should
not be taking any traps at this point, especially FPU.
