/*
|
|
* 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.
