Subject: [PATCH 09/10] imx-bbu-nand-fcb: Erase whole partition
Date: Fri, 12 Jun 2015 08:35:45 +0200	[thread overview]
Message-ID: <1434090946-6574-10-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1434090946-6574-1-git-send-email-s.hauer@pengutronix.de>

Now that we use a partition for the bootloader instead of
the whole NAND device we can erase it completely instead of
hardcoded 2MB.
