Is there something to look for? Except for "it > works"? As this code touches the earlycon functionality, of interest are the 3 cases highlighted above: 1/ "earlycon keep_bootcon" are both present in bootargs 2/ only "earlycon" is present in bootargs 3/ none of the "earlycon" or "earlycon keep_bootcon" are present in bootargs One other thing, that I was currently able to test only on RZ/G3S, is to see how it behaves when the debug serial is described in DT with an alias other than zero. E.g., on [1] the debug serial alias on RZ/G3S was changed from 0 to 3. With the new alias (3) there were issues that I've tried to fix with this series.
