[PATCH 0/2] pcie-designware: add iATU unroll feature
From: Joao Pinto
Date: Thu Jul 21 2016 - 05:48:46 EST
The new DWC PCIe Core version (4.80) implements iATU in a different way.
This new mechanism is called iATU Unroll Mode. The Core still supports
the "old" mechanism calling it Legacy Mode if configured to do so, but
the standard way will be using Unroll.
This patch adds the necessary support for the mechanism and makes
some minor improvements to the existent one.
