    MIPS: CPS: Have asm/mips-cps.h include CM & CPC headers · e83f7e02
    Paul Burton authored
    With Coherence Manager (CM) 3.5 information about the topology of the
    system, which has previously only been available through & accessed from
    the CM, is now also provided by the Cluster Power Controller (CPC). This
    includes a new CPC_CONFIG register mirroring GCR_CONFIG, and similarly a
    new CPC_Cx_CONFIG register mirroring GCR_Cx_CONFIG.
    In preparation for adjusting functions such as mips_cm_numcores(), which
    have previously only needed to access the CM, to also access the CPC
    this patch modifies the way we use the various CPS headers. Rather than
    having users include asm/mips-cm.h or asm/mips-cpc.h individually we
    instead have users include asm/mips-cps.h which in turn includes
    asm/mips-cm.h & asm/mips-cpc.h. This means that users will gain access
    to both CM & CPC registers by including one header, and most importantly
    it makes asm/mips-cps.h an ideal location for helper functions which
    need to access the various components of the CPS.
