Subject: ARM: OMAP2+: nand: Fix NAND on OMAP2 and OMAP3 boards
From: Roger Quadros <rog...@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)
