Not sure if AXI will be relevant bus name to manage newer Broadcom IP
cores. Yes, AMBA AXI is underlying interconnect used for communications,
but those communications are made in regard of communication ports
(those thingys referenced at Broadcom code as wrappers and which are
actually master ports intermediately bound to the backplane itself).
Pretty much sure your original bcmb is much more relevant for managing
Broadcom hardware extensions over AXI than just axi, especially
considering that techniques we use to identify, enumerate and control
AXI slave ports are completely Broadcom-specific.

Have nice day,
George
