Subject[PATCH v3 6/6] ARM: dts: vf-colibri: enable NAND flash controller
Date
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.
