Is this a hardware limitation, > or did you just forget to add it? I don't have enough technical documentation at the moment to answer the question. Would it be possible to merge this as-is, and update it later on when we have enough information about 64-bit MMIO area support? It does not affect this new DT binding, since it's purely related to the standard PCI binding. Would this be OK? I'd prefer to have PCI supported with just the 32 bits non-prefetchable memory rather than no PCI supported at all. Thanks a lot!
