  30/*
  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.
