freebsd/sys/contrib/octeon-sdk/executive-config.h.template
Juli Mallett 219d14fe5f Import the Cavium Simple Executive from the Cavium Octeon SDK. The Simple 
Executive is a library that can be used by standalone applications and kernels
to abstract access to Octeon SoC and board-specific hardware and facilities.
The FreeBSD port to Octeon will be updated to use this where possible.

* should have an executive-config.h file in a directory named 'config'.
* If the application uses other components, config files for those
* components should be placed in the config directory as well. The
* macros defined in this file control the configuration and functionality
* provided by the simple executive. Available macros are commented out
* and documented in this file.
