From ab493a0f0f55d28636ac860ea682d57b84257f10 Mon Sep 17 00:00:00 2001 From: Ohad Ben-Cohen Date: Thu, 2 Jun 2011 02:48:05 +0300 Subject: drivers: iommu: move to a dedicated folder Create a dedicated folder for iommu drivers, and move the base iommu implementation over there. Grouping the various iommu drivers in a single location will help finding similar problems shared by different platforms, so they could be solved once, in the iommu framework, instead of solved differently (or duplicated) in each driver.
