Subject: [PATCH 3/3] serial/8250: delete WR SBC850 UART quirk handling
Date: Tue, 26 Jun 2012 15:54:29 -0400	[thread overview]
Message-ID: <1340740469-31445-4-git-send-email-paul.gortmaker@windriver.com> (raw)
In-Reply-To: <1340740469-31445-1-git-send-email-paul.gortmaker@windriver.com>

We've are dropping the support for the EOL SBC8560, so we can
also delete this variant of the Alpha quirk support.
