Help text

The Huawei Cache Coherence System (HCCS) is a multi-chip interconnection bus protocol. The performance of application may be affected if some HCCS ports are not in full lane status, have a large number of CRC errors and so on. This may support for reducing system power consumption if there are HCCS ports supported low power feature on platform.

Say M here if you want to include support for querying the health status and port information of HCCS, or reducing system power consumption on Kunpeng SoC.
