Subject: [PATCH] ARM: dts: armada-38x: add buffer manager nodes
|
||
|
|
|
||
|
|
Armada 38x network controller supports hardware buffer management (BM).
|
||
|
|
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.
