tools: kwboot: Allow to specify custom baudrate only in supported operations
Custom baudrate different than 115200 may be specified only when kwboot is not going to send boot/debug message pattern or when it is going to send boot message pattern with image file (in which case baudrate change happens after sending kwbimage header). BootROM detects boot/debug message pattern only at baudrate 115200. Signed-off-by: Pali Rohár <pali@kernel.org> Reviewed-by: Stefan Roese <sr@denx.de>
