-Subject: [RFC] serial: core: add support for boot console with arbitrary
- baud rates
-
-The Arduino Yun uses a baud rate of 250000 by default. The serial is
-going over the Atmel ATmega and is used to connect to this chip.
-Without this patch Linux wants to switch the console to 9600 Baud.
-
-With this patch Linux will use the configured baud rate and not a
-default one specified in uart_register_driver().
