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.
