I don't think that moving the nand partition to the carrier board dtsi is 
correct.
The nand partition does not have anything to do with the carrier board in first 
place.
So they should rather be moved to the am335x-wega-rdk.dts which does describe 
the 
board in a whole. 
If you do this, you should remove the spi partitions from the SoM dtsi also.

And it is generally possible to delete nodes from a device tree with 
/delete-node/ _node; 
But I have actually not tested this when overwriting partitions. Neither know 
if this whould
be a sane solution.

Regards
Teresa
