From 78c112c9f9eb3cd06ea53e1c414cabc55560e9cd Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 5 Dec 2012 14:46:43 +0000 Subject: console: Enable function to display console info The CONFIG_SYS_CONSOLE_INFO_QUIET option should suppress the console information, but allow boards to display it later if required. Adjust the code to support this. This is used to avoid printing the information while the LCD display is not ready, since it only becomes ready when stdio init is complete.
