From: "Gupta, Pekon" <pekon@xxxxxx> [Change v1 -> v2] added [PATCH 3/4] and [PATCH 4/4] [PATCH 1/4]: clean-up and optimization for supported ECC schemes. [PATCH 2/4]: add separate DT options each supported ECC scheme. [PATCH 3/4]: update BCH4 ECC implementation (using ELM or using lib/bch.h) [PATCH 4/4]: update DT attribute for ti,nand-ecc-opt After this patch series, omap2-nand driver will supports following ECC schemes: +---------------------------------------+---------------+---------------+ | ECC scheme |ECC calculation|Error detection| +---------------------------------------+---------------+---------------+ |OMAP_ECC_HAMMING_CODE_DEFAULT |S/W |S/W | |OMAP_ECC_HAMMING_CODE_HW |H/W (GPMC) |S/W | |OMAP_ECC_HAMMING_CODE_HW_ROMCODE |H/W (GPMC) |S/W | +---------------------------------------+---------------+---------------+ |OMAP_ECC_BCH4_CODE_HW_DETECTION_SW |H/W (GPMC) |S/W (lib/bch.h)| |OMAP_ECC_BCH4_CODE_HW |H/W (GPMC) |H/W (ELM) | +---------------------------------------+---------------+---------------+ |OMAP_ECC_BCH8_CODE_HW_DETECTION_SW |H/W (GPMC) |S/W (lib/bch.h)| |OMAP_ECC_BCH8_CODE_HW |H/W (GPMC) |H/W (ELM) | +---------------------------------------+---------------+---------------+ - Selection of OMAP_ECC_BCHx_CODE_HW_DETECTION_SW requires, Kconfig: CONFIG_MTD_NAND_ECC_BCH: enables S/W based BCH ECC algorithm. - Selection of OMAP_ECC_BCHx_CODE_HW requires, Kconfig: CONFIG_MTD_NAND_OMAP_BCH: enables ELM H/W module.
