Sure, here you go:

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

[stefan at 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 at 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
