For a new subarchitecture, using DT is required, but it should not make your work harder. spear3xx/6xx is a good example of an older platform that was recently converted (take the arm-soc tree as a base, it contains the latest version). Another good one would be highbank, but that contains a lot of stuff you don't need. ixp4xx is not very actively maintained, so I would not use that as a base. What platform are you talking about? I know of a few people that are working on getting older platforms ported to Linux, so maybe someone is already working on a port. Arnd
