Subject: [PATCH 09/15] mini2440: Configure debug UART pins very early
Date: Sun, 13 Feb 2011 15:10:46 +0100	[thread overview]
Message-ID: <1297606252-802-10-git-send-email-jbe@pengutronix.de> (raw)
In-Reply-To: <1297606252-802-1-git-send-email-jbe@pengutronix.de>

From: Juergen Beisert <juergen@kreuzholzen.de>

This is required in order to enable booting from NAND and to avoid any visible
garbage on the screen until the pins are really set.
