Subject: [PATCH 04/20] MACH-S3C24XX: Add support for flash based BBT
Date: Wed, 16 Feb 2011 19:13:29 +0100 [thread overview]
Message-ID: <1297880025-7184-5-git-send-email-jbe@pengutronix.de> (raw)
In-Reply-To: <1297880025-7184-1-git-send-email-jbe@pengutronix.de>
From: Juergen Beisert <juergen@kreuzholzen.de>
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.
