Subject: [PATCH 1/9] PBL: Add strnlen, needed for printf support
Date: Tue,  9 Dec 2014 19:17:36 +0100	[thread overview]
Message-ID: <1418149064-26448-2-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1418149064-26448-1-git-send-email-s.hauer@pengutronix.de>

vsprintf needs strnlen, so in oder to add console support to
the PBL we need a strnlen implementation.
