Jetson TK1 board support

Hi,

I have collected the patches to run FreeBSD on Jetson TK1
in the following archive:

http://www.staff.uni-mainz.de/weiss/jetson-tk1.tgz

Part of it is not pretty, but the system is able to
do a buildworld with -j6 and src and obj over nfs
without problems. I think it is at least a starting
point for further work.

Regards

Juergen
