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.
Thanks!
Thomas
