From a2a55e518f81900ab1538656e5df8d2759ccb1fb Mon Sep 17 00:00:00 2001 From: Prabhakar Kushwaha Date: Thu, 19 Mar 2015 09:20:45 -0700 Subject: driver/fsl-mc: Add support of MC Flibs Freescale's Layerscape Management Complex (MC) provide support various objects like DPRC, DPNI, DPBP and DPIO. Where: DPRC: Place holdes for other MC objectes like DPNI, DPBP, DPIO DPBP: Management of buffer pool DPIO: Used for used to QBMan portal DPNI: Represents standard network interface These objects are used for DPAA ethernet drivers.
