I checked by quickly starting a terminal app and it does not seem that

BUT:
The tests I did in this mail were done with your 39 patches applied
on top of "master-kwboot" [1]. Here booting with 115k works as explained
below.

Now I applied the same 39 patches on top of "next" [2]. And here not
even booting with 115k works on my AXP target. It always hangs at this
stage:


So default baudrate 115200 works fine on master+39patches and does not
work on next+39patches? Could you check if it works on next without
applying any patch?


Sure, here you go:

First the test on "next" without the 39 patches:

[stefan@ryzen u-boot (next)]$ ./tools/kwboot -p -b u-boot-spl.kwb -t/dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A1019EGY-if00-port0

Sending boot message. Please reboot the target...|

Not working!

And now test on "master" without the 39 patches:

[stefan@ryzen u-boot (master)]$ ./tools/kwboot -p -b u-boot-spl.kwb -t/dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A1019EGY-if00-port0

Seems to okay.
