+Subject: [PATCH] ARM: dts: armada-38x: enable buffer manager support on Armada
+ 38x boards
+
+Since mvneta driver supports using hardware buffer management (BM), in
+order to use it, board files have to be adjusted accordingly. This commit
+enables BM on:
+* A385-DB-AP - each port has its own pool for long and common pool for
+short packets,
+* A388-ClearFog - same as above,
+* A388-DB - to each port unique 'short' and 'long' pools are mapped,
+* A388-GP - same as above.
+
+Moreover appropriate entry is added to 'soc' node ranges, as well as "okay"
+status for 'bm' and 'bm-bppi' (internal SRAM) nodes.
