Subject: [PATCH v6 4/5] ARM: OMAP: gpmc: enable hwecc for AM33xx SoCs
Date: Thu, 29 Nov 2012 17:01:31 +0100 [thread overview]
Message-ID: <1354204892-22762-5-git-send-email-zonque@gmail.com> (raw)
In-Reply-To: <1354204892-22762-1-git-send-email-zonque@gmail.com>
The am33xx is capable of handling bch error correction modes, so
enable that feature in the driver.
