From b050898efa6b4f0272f12885a7365f044ab4c08e Mon Sep 17 00:00:00 2001 From: Ash Charles Date: Wed, 18 Feb 2015 11:25:11 -0800 Subject: omap: gpmc: 'nandecc sw' can use HAM1 or BCH8 The 'nandecc sw' command selects a software-based error correction algorithm. By default, this is OMAP_ECC_HAM1_CODE_SW but some platforms use OMAP_ECC_BCH8_CODE_HW_DETECTION_SW as their software-based correction algorithm. Allow a user to be specific e.g. # nandecc sw where 'hamming' is still the default. Note: we don't just use CONFIG_NAND_OMAP_ECCSCHEME as it might be set to a hardware-based ECC scheme---a little strange when the user has requested 'sw' ECC.
