Yes. I would actually been interested in a summary/conclusion of the discussions, because I'm not sure what I'm supposed to do now. So there are two parts here: * Mapping PCIe I/O regions as strongly ordered. * Disabling outer_cache sync in the PL310 driver. Some discussion has been going on with Catalin, I've answered some questions by providing more details to Catalin, but in the end, I don't know if the patches I provided are acceptable or not, and if not, in what way they should be changed.
