+ SC7180 interconnect providers support system bandwidth requirements
through
+ RPMh hardware accelerators known as Bus Clock Manager (BCM). The
provider is
+ able to communicate with the BCM through the Resource State
Coordinator (RSC)
+ associated with each execution environment. Provider nodes must
point to at
+ least one RPMh device child node pertaining to their RSC and each
provider
+ can map to multiple RPMh resources.
