Due to lack of version numbers or other names I call them old and new here :). The newer one supports rx fifo mode, whereas the older one doesn't. The mainline flexcan driver just supports the new core [1]. The older core is found on coldfire processors. I don't know if there are coldfire cpus with the new flexcan core, too. The driver can be adopted to the old core if needed. The first cpus with the new core I got in touch with was the mx35 (arm11) and mx25 (arm9) both at the same time. Ask fsl which one was released first. After this there was mx28 (arm9) and there should be an mx53 (coretexa8) with flexcan too. > Other than an agreement on the compatible property, I believe we have > agreement on all the other code changes in these patches.
