This is not a configuration. When on-demand page is enabled
then we must do a two pass link: The first pass creates an
intermediate object that has all of the code that must be
placed in the locked memory partition. This is logic that

The directory contains the logic necessary to do the platform
specific first pass link for the EA313x.

Configures the NuttShell (nsh) located at examples/nsh. The
Configuration enables only the serial NSH interface.
