Sonic Inc. Silicon Backplane driver
To compile this driver into the kernel, add the following lines to the kernel
To load the driver as a module at boot, add this line to
support for devices based on the Sonic Inc. Silicon Backplane, an interblock
communications architecture found in earlier Broadcom Home Networking Division
wireless chipsets and embedded systems.
A common interconnect connects all of the Silicon Backplane's functional blocks.
These functional blocks, known as cores, use the Open Core Protocol (OCP)
interface to communicate with agents attached to the Silicon Backplane.
Each core can have an initiator agent that passes read and write requests onto
the system backplane and a target agent that returns responses to those
requests. Not all cores contain both an initiator and a target agent.
Initiator agents are present in cores that contain host interfaces (PCI,
PCMCIA), embedded processors (MIPS), or DMA processors associated with
