Hi Simon, I'll gladly do that, but I haven't write and use any test in U-Boot. So it is a bit foggy how to implement it. Do we want to create a fake device-tree and test each configuration or do we want to test in the _current_ device-tree if timings are correctly set according to the index value ?
