51 support for devices based on the Sonic Inc. Silicon Backplane, an
52 interblock communications architecture found in earlier Broadcom Home
53 Networking Division wireless chipsets and embedded systems.
55 A common interconnect connects all of the Silicon Backplane's functional
57 These functional blocks, known as cores, use the Open Core Protocol
58 (OCP) interface to communicate with agents attached to the Silicon
61 Each core can have an initiator agent that passes read and write
62 requests onto the system backplane and a target agent that returns
63 responses to those requests.
64 Not all cores contain both an initiator and a target agent.
65 Initiator agents are present in cores that contain
66 host interfaces (PCI, PCMCIA), embedded processors (MIPS),
67 or DMA processors associated with communications cores.
