From 8fb54284ba6aa1f0d832ec015fde64ecf4bb0f4f Mon Sep 17 00:00:00 2001 From: Santosh Shilimkar Date: Tue, 28 Jun 2011 12:42:56 -0700 Subject: ARM: mm: Add strongly ordered descriptor support. On certain architectures, there might be a need to mark certain addresses with strongly ordered memory attributes to avoid ordering issues at the interconnect level. On OMAP4, the asynchronous bridge buffers can only be drained with strongly ordered accesses and hence the need to mark the memory strongly ordered.
