From 4ecd42f9b52cd01b659c21f62e5ca2e79f5da4ab Mon Sep 17 00:00:00 2001 From: Julien Viard de Galbert Date: Tue, 20 Feb 2018 15:01:27 +0100 Subject: console: Introduce a way for mainboard to override the loglevel This change adds a config option to allow mainboard to override the console loglevel. When the option is set, the platform has to define the function get_console_loglevel returning a valid loglevel value. This allows a mainboard to sample a GPIO to switch the loglevel value between different environments (qualification vs production) without re-flashing.
