From 6d9e44986891345636e2d6069c4ae1612b2337d4 Mon Sep 17 00:00:00 2001 From: Sonic Zhang Date: Wed, 27 Oct 2010 04:16:49 -0400 Subject: [PATCH] serial: bfin_5xx: disable CON_PRINTBUFFER for consoles 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.
