[PATCH 2.6] Cobalt 2/2: add support for Qube2700

To: linux-mips@linux-mips.org
Subject: [PATCH 2.6] Cobalt 2/2: add support for Qube2700
From: Peter Horton <pdh@colonel-panic.org>
Date: Tue, 1 Mar 2005 08:41:38 +0000
Cc: ralf@linux-mips.org
Original-recipient: rfc822;linux-mips@linux-mips.org
Sender: linux-mips-bounce@linux-mips.org
User-agent: Mutt/1.5.6+20040907i
On Qube2700 Galileo hangs if we access slot #6.

Make console serial port initialisation dependent on unit type.

P.
