<p class="Pp">The <code class="Nm">bcma</code> driver provides
    <a class="Xr">bhnd(4)</a> support for devices using the ARM AMBA-based
    backplane architecture found in later Broadcom Home Networking Division's
    network chipsets and embedded systems.</p>
<p class="Pp">A common interconnect connects all of the backplane's functional
    blocks. These functional blocks, known as cores, use the ARM AMBA AXI or APB
    interface to communicate with devices attached to the interconnect.</p>
<p class="Pp">The IP cores used in <a class="Xr">siba(4)</a> devices were
    adapted by Broadcom for compatibility with the new interconnect.</p>
