This patch removes most of the #ifdefs in libc/console.c, and
replaces it with two queues (input, output) where drivers (serial, keyboard, video, usb) can attach. The only things left with #ifdefs are initialization (at some point the drivers must get a chance to register) Signed-off-by: Patrick Georgi <patrick.georgi@coresystems.de> Acked-by: Jordan Crouse <jordan.crouse@amd.com> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@3679 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
