MIPS: Coherent Processing System SMP implementation
This patch introduces a new SMP implementation for systems implementing the MIPS Coherent Processing System architecture. The kernel will make use of the Coherence Manager, Cluster Power Controller & Global Interrupt Controller in order to detect, bring up & make use of other cores in the system. SMTC is not supported, so only a single TC per VPE in the system is used. That is, this option enables an SMVP style setup but across multiple cores.
