[PATCH 16/19] serial: bfin_5xx: disable CON_PRINTBUFFER for consoles

From: Greg Kroah-Hartman
Date: Fri Nov 12 2010 - 16:41:59 EST


From: Sonic Zhang <sonic.zhang@xxxxxxxxxx>

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.
