.Dd June 3, 2016 .Dt BCMA 4 .Os .Sh NAME .Nm bcma .Nd Broadcom AMBA Backplane driver .Sh SYNOPSIS To compile this driver into the kernel, place the following lines in your kernel configuration file: d -ragged -offset indent .Cd "device bhnd" .Cd "device bcma" .Ed
p Alternatively, to load the driver as a module at boot time, place the following line in .Xr loader.conf 5 : d -literal -offset indent bcma_load="YES" .Ed .Sh DESCRIPTION The .Nm driver provides .Xr bhnd 4 support for devices using the ARM AMBA-based backplane architecture found in later Broadcom Home Networking Division's (HND) wireless chipsets and embedded systems.
p 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 The IP cores used in .Xr siba 4 devices were adapted by Broadcom for compatibility with the new interconnect. .Sh SEE ALSO .Xr bhnd 4 .Sh HISTORY The .Nm device driver first appeared in .Fx 11.0 . .Sh AUTHORS .An -nosplit The .Nm driver was written by .An Landon Fuller Aq Mt landonf@FreeBSD.org .
