* Performance event support - hardware-specific disambiguation
*
* For now this is a compile-time decision, but eventually it should be
* runtime. This would allow multiplatform perf event support for e300 (fsl
* embedded perf counters) plus server/classic, and would accommodate
* devices other than the core which provide their own performance counters.
