Doesn't change anything. In fact the tty is already configured for
115200 Baud. And I would expect that on a mismatch it wouldn't always
die just after the header is uploaded.

Just noticed that my binary.0 was corrupted as I extraced it from a nand
dump that also included the oob area ...

With a proper image I get barebox up now.

This is still not explained. I would have expected that this select
doesn't do anything noticable on the remote end.

Just for the log: UART = 0x69.
