DESCRIPTION
Thebcma driver provides
bhnd(4) support for devices using the ARM AMBA-based backplane
architecture found in later Broadcom Home Networking Division's network
chipsets and embedded systems.
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.
The IP cores used in siba(4) devices were adapted by Broadcom for compatibility with the new interconnect.
