Subject: [PATCH v4 6/6] ARM: dts: vf-colibri: enable NAND flash controller
Date: Wed, 25 Mar 2015 17:28:29 +0100 [thread overview]
Message-ID: <1427300909-20825-7-git-send-email-stefan@agner.ch> (raw)
In-Reply-To: <1427300909-20825-1-git-send-email-stefan@agner.ch>
Enable NAND access by adding pinmux and NAND flash controller node
to device tree. The NAND chips currently used on the Colibri VF61
requires 8-bit ECC per 512 byte page, hence specify 32-bit ECC
strength per 2k page size.
