Subject: mini2440: Forgotten patches to make it work (2 of 2)
Date: Sun, 13 Feb 2011 20:49:19 +0100 [thread overview]
Message-ID: <201102132049.20291.jbe@pengutronix.de> (raw)
In-Reply-To: <201102132001.04701.jbe@pengutronix.de>
From: Juergen Beisert <juergen@kreuzholzen.de>
Subject: MACH-S3C24XX: Add support for flash based BBT
The default configuration of the current 2.6.37 kernel uses a flash based BBT.
So, barebox must also use one, to be in sync with the kernel about bad blocks
in the flash.
Due to the used OOB layout, the generic BBT description coming with the
framework can be used.
