From f5c3ba79788b0e39baab7026d374fe375dd1a43f Mon Sep 17 00:00:00 2001 From: Mark Jackson Date: Mon, 25 Aug 2008 19:21:30 +0100 Subject: [PATCH] Allow console input to be disabled Added new CONFIG_DISABLE_CONSOLE define and GD_FLG_DISABLE_CONSOLE. When CONFIG_DISABLE_CONSOLE is defined, setting GD_FLG_DISABLE_CONSOLE disables all console input and output.
