4.1-ti supports overlays, so you can either do it like "3.8".

https://github.com/beagleboard/bb.org-overlays/blob/master/src/arm/BB-UART1-00A0.dts

or create a custom *.dtb

[beagleboard] How to enable UART1 using dtb-rebuilder?

[Davide Picchi]

I was able to enable all the UART serial connections on my BBB before I 
switched to the last kernel.
In the following tutorial 
it was explained 
very well, how to change the cape-fuctions accordingly and everything 
worked fine.

Now I have the latest Ubuntu distro on my board. I ve downloaded the last 
dtb-rebuilder 
for 4.1-ti  and try to 
enable again my old uart ports.
It seems that everything is changed since 3.8. I open my 
am335x-boneblack-dts, but I can find any 
#include

directive which helps to activate/deactivate peripherals.

The readme in the repository says nothing about that.

What should I do? 
How can I compile my dtb-file for my board?
