Hi, Matthias, Arnd, After previous discussion[1], I'm not sure which one do you preferred for mt8127/mt8135, so I send 64bits address version again. Trying to not SPAM too much, I only send the difference(first 4 patches) this time. We do have SoC that need >4GB address, so at least those will need to use 64bits address. If we want to have a consistent look, 64bits is the way to go. Also we already have some patches under review now using 64bits address. So I preferred this one, but both versions are OK to me. Please help to review this and let me know anything you want me to change. Thanks.
