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.
