From 722202e10b488c14e93c428743a0e476093949e3 Mon Sep 17 00:00:00 2001 From: Gregory CLEMENT Date: Fri, 12 Oct 2012 17:59:48 +0200 Subject: arm: plat-orion: Add coherency attribute when setup mbus target Recent SoC such as Armada 370/XP came with the possibility to deal with the I/O coherency by hardware. In this case the transaction attribute of the window must be flagged as "Shared transaction". Once this flag is set, then the transactions will be forced to be sent through the coherency block, in other case transaction is driven directly to DRAM.
