Hello Vagrant,
Attached is a patch to enable support for the Jetson Tegra K1 board via a new
u-boot-tegra package. It is based on the experimental-2015.07 branch of git. I
can push it myself if you prefer but I thought I'd best have it reviewed first.
I'm not entirely happy with the requirement (documented in the README) to use
L4T to do the flashing but I've not yet worked out a fully working alternative
(I think something must be possible using some combination of tegracrm and
cbotimage both of which are in Debian, but I've not figured out the exact steps
yet).
Cheers,
Ian.

+== Installation ==
+
+At this point, you must install U-Boot to flash yourself from a host
+system using the Linux_For_Tegra tools.
+
+sudo ./flash.sh -L /usr/lib/u-boot/jetson-tk1/u-boot-dtb-tegra.bin jetson-tk1 mmcblk1p1
+
+It seems that L4T R19.3.0 is currently required (image does not boot

+
+== U-Boot environment tools ==
+
+fw_printenv / fw_setenv read /etc/fw_env.config for configuration.
