  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.
