+The console driver for the UARTs will always be set to a baud rate
+of 115200 with 8 bit characters, 1 stop bit and no parity bits
+during start up.
+Previous configurations programmed into the hardware by the Xilinx
+tools or a bootloader will be overwritten.
+
+The settings for parity and stop bits can be changes by the user
+application. The baud rate is hard coded to 115200 and can not be
+changed.
