 /*
  * The defines below should be used with the OCTEON_IS_MODEL() macro
  * to determine what model of chip the software is running on.	Models
  * ending in 'XX' match multiple models (families), while specific
  * models match only that model.  If a pass (revision) is specified,
  * then only that revision will be matched.  Care should be taken when
  * checking for both specific models and families that the specific
  * models are checked for first.  While these defines are similar to
  * the processor ID, they are not intended to be used by anything
  * other that the OCTEON_IS_MODEL framework, and the values are
  * subject to change at anytime without notice.
  *
  * NOTE: only the OCTEON_IS_MODEL() macro/function and the OCTEON_CN*
  * macros should be used outside of this file.	All other macros are
  * for internal use only, and may change without notice.

	* The defines below should be used with the OCTEON_IS_MODEL() macro
	* to determine what model of chip the software is running on. Models
	* ending in 'XX' match multiple models (families), while specific
	* models match only that model. If a pass (revision) is specified,
	* then only that revision will be matched. Care should be taken when
	* checking for both specific models and families that the specific
	* models are checked for first. While these defines are similar to
	* the processor ID, they are not intended to be used by anything
	* other that the OCTEON_IS_MODEL framework, and the values are
	* subject to change at anytime without notice.

	* NOTE: only the OCTEON_IS_MODEL() macro/function and the OCTEON_CN*
	* macros should be used outside of this file. All other macros are
