How to create a custom board file for the nRF9160

I am trying to create a custom board file in the ncs/zepher/boards directory for our nRF9160.

If I copy the nrf9160_pca10090 directory to a new nam eg. nrf9160_newboard it will compile and run just fine.

Then when i change the name of the files to nrf9160_newboard and change the references in each of the files to correspond to the new file names.

I was able to get the hello world example to compile and run as a nrf9160_newboard, but when I tried to compile as nrf9160_newboardns I get the following errors in spm.c

i tried this using a grep replace function for 10090 on the new directory since I though I may have missed a line somewhere.

Is there a tutorial or set of directions on how to create new boards other than the one in Zephyr.

(Note: I did this before the introduction of the secure and non-secure versions of the board for section placement)
