There is a large number of varieties of CPUs - things like cache size, cache line size, architectural extension and many small details of behaviour differ. If we'd fully honor DT CPU configuration information a kernel would need to have fairly full blown generic CPU support for anything under the sun. But there already is a scheme that allows platform support code to select permanet enablement, disablement or runtime probe for every CPU feature under the sun for significant code savings and performance gain.
