Subject: [PATCH 3/4] serial: bfin_5xx: disable CON_PRINTBUFFER for consoles
Date: Wed, 27 Oct 2010 04:16:49 -0400	[thread overview]
Message-ID: <1288167410-31554-4-git-send-email-vapier@gentoo.org> (raw)
In-Reply-To: <1288167410-31554-1-git-send-email-vapier@gentoo.org>

From: Sonic Zhang <sonic.zhang@analog.com>

If we are using early serial, don't let the normal console rewind
the log buffer, since that causes things to be printed multiple times.
