I see here rather random set of changes in each version of this patch.
This does not really make sense. You are saying that existing (!!!)
mpfs-sd4hc is compatible with sd6hc. I think you wanted oneOf here, but
not sure. Can you explain what is your intention? Your commit msg is
just one line saying the same as subject, so not really helpful.
