From 7aac3015b533add3e85222f9fd2ab66216b38746 Mon Sep 17 00:00:00 2001 From: Joe Millenbach Date: Thu, 19 Jul 2012 18:04:39 -0700 Subject: [PATCH] x86, boot: Switch output functions from command-line flags to conditional compilation Changed putstr flagging from parameter to conditional compilation for puts, debug_putstr, and error_putstr. This allows for space savings since most configurations won't use this feature.
