From 235daa4bf6b6467b5df675dcfe5041b7f62eeae3 Mon Sep 17 00:00:00 2001 From: Julien Viard de Galbert Date: Tue, 20 Feb 2018 11:45:48 +0100 Subject: driver/uart: Introduce a way for mainboard to override the baudrate The rationale is to allow the mainboard to override the default baudrate for instance by sampling GPIOs at boot. A new configuration option is available for mainboards to select this behaviour. It will then have to define the function get_uart_baudrate to return the computed baudrate.
