NAME
     siba - Sonic Inc. Silicon Backplane driver

SYNOPSIS
     To compile this driver into the kernel, place the following lines in your
     kernel configuration file:

           device bhnd
           device siba

     Alternatively, to load the driver as a module at boot time, place the
     following line in loader.conf(5):

           siba_load="YES"

DESCRIPTION
     The siba driver provides bhnd(4) 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 communications cores.

HISTORY
     The siba device driver first appeared in FreeBSD 8.0.  The driver was
     rewritten for FreeBSD 11.0.  to support the common Broadcom bhnd(4) bus
     interface.
