Subject: [PATCH v7 4/5] ARM: OMAP: gpmc: enable hwecc for AM33xx SoCs
Date: Wed,  5 Dec 2012 20:09:30 +0100	[thread overview]
Message-ID: <1354734571-10774-5-git-send-email-zonque@gmail.com> (raw)
In-Reply-To: <1354734571-10774-1-git-send-email-zonque@gmail.com>

The am33xx is capable of handling bch error correction modes, so
enable that feature in the driver.
