Hi Mikhail,

The /chosen node should be created and populated by the fdt support to 
reflect the board's hardware.  If you run the "fdt chosen" command, you 
should see what is created.  If it isn't created, you are missing a 
setup piece in your board support customization.

Having a /chosen node in the DTS is deprecated.
