Since it is now enabled in mvneta driver, appropriate nodes can be added to armada-38x.dtsi - for the actual common BM unit (bm@c8000) and its internal SRAM (bm-bppi), which is used for indirect access to buffer pointer ring residing in DRAM. Pools - ports mapping, bm-bppi entry in 'soc' node's ranges and optional parameters are supposed to be set in board files.
