	This patch adds a minimal framework for Dickens CCN-504 interconnect configuration - mainly related to adding Clusters/cores to snoop/DVM domain and setting QoS of the RN-I ports. LS2085A platform makes use of these configurations to support better network data performance and to boot a SMP Linux.
