31  * The defines below should be used with the OCTEON_IS_MODEL() macro
32  * to determine what model of chip the software is running on.	Models
33  * ending in 'XX' match multiple models (families), while specific
34  * models match only that model.  If a pass (revision) is specified,
35  * then only that revision will be matched.  Care should be taken when
36  * checking for both specific models and families that the specific
37  * models are checked for first.  While these defines are similar to
38  * the processor ID, they are not intended to be used by anything
39  * other that the OCTEON_IS_MODEL framework, and the values are
40  * subject to change at anytime without notice.
41  *
42  * NOTE: only the OCTEON_IS_MODEL() macro/function and the OCTEON_CN*
43  * macros should be used outside of this file.	All other macros are
44  * for internal use only, and may change without notice.
