Cover letter [PATCH 0/2] pcie/designware: Viewport assignment update
Most of the designware PCIe platforms have more than 2 viewports. So, patch 1/2 allows to fix viewport-2 for IO transaction for such cases. When we have only two viewports, then patch 2/2 exchange viewport assignment of memory and cfg transaction. It helps to fix a possibility of corruption for memory transaction. However, there still exist possibility of an IO transaction to be corrupted. We can not do much for <=2 viewports. See, patch log for detail.
