/*

* NOTE: These must match what is checked in common-config.mk

* Defines to represent the different versions of Octeon.
|
|
*
|
|
* IMPORTANT: When the default pass is updated for an Octeon Model,
|
|
* the corresponding change must also be made in the oct-sim script.
|
|
*
|
|
* 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
|
|
