No need. It just wasn't clear to me that you had U-Boot configured to
pass the rate on the command line.
As I mentioned, I suspect that the serial output doesn't "die" as such,
but rather changes rate. It might be worth clarifying that in the commit
message, but either way the patch itself is fine, and it's no big deal.
Thanks,
Mark.
