/*
 * 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.
