This file contains the configuration parameters for the template BSP.
This template starts simple - with most facilities excluded by default.

TODO -
Present the user with simple straight forward options.  Do not ask the
user to encode values together to form a value to be loaded in a register.
Let the source code, or the pre-processor, do the computational work to
determine what value to load in a particular register.
