39 | * The defines below should be used with the OCTEON_IS_MODEL() macro | |
40 | * to determine what model of chip the software is running on. Models | |
41 | * ending in 'XX' match multiple models (families), while specific | |
42 | * models match only that model. If a pass (revision) is specified, | |
43 | * then only that revision will be matched. Care should be taken when | |
44 | * checking for both specific models and families that the specific | |
45 | * models are checked for first. While these defines are similar to | |
46 | * the processor ID, they are not intended to be used by anything | |
47 | * other that the OCTEON_IS_MODEL framework, and the values are | |
48 | * subject to change at anytime without notice. | |
