3.13.11.4 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Roger Quadros <rogerq@ti.com>

commit 5005e0b76781c37d0a16dd6dd17d015098e8ce92 upstream.

Commit c66d039197e4 broke NAND for non-DT boot on all OMAP2 and OMAP3
boards using board_nand_init(). Following error is seen at boot

[    0.154998]  (null): Unsupported NAND ECC scheme selected

For OMAP2 and OMAP3 platforms, the ecc_opt parameter in platform data
must be set to OMAP_ECC_HAM1_CODE_HW to work properly.

Tested on omap3-beagle c4.

Fixes: c66d039197e4 (mtd: nand: omap: combine different flavours of 1-bit hamming ecc schemes)
