Subject: [PATCH v4 3/5] ARM: ep93xx: ts72xx: Rewrite map IO code to be reusable
Date:   Fri,  1 Dec 2017 00:51:38 +0100
Message-Id: <20171130235140.12243-4-lukma@denx.de>
In-Reply-To: <20171130235140.12243-1-lukma@denx.de>
References: <20171116232239.16823-1-lukma@denx.de>
 <20171130235140.12243-1-lukma@denx.de>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The map IO common code has been excluded to be reused by other ts72xx
clones.
