/* 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.
