[PATCH 3.13 167/212] ARM: OMAP2+: nand: Fix NAND on OMAP2 and OMAP3 boards
From: Kamal Mostafa
Date: Tue Jun 17 2014 - 18:21:53 EST
3.13.11.4 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Roger Quadros <rogerq@xxxxxx>
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)
