Changes v4 -> v5 - Rebased to linux-next IMPORTANT: Need to revert commit fb1585b, [PATCH 2/4] part of previous version http://lists.infradead.org/pipermail/linux-mtd/2013-July/047441.html - Swapped PATCH-1 & PATCH-2 to maintain bisectibility & compilation dependency http://lists.infradead.org/pipermail/linux-mtd/2013-July/047461.html - PATCH-2: re-ordered call to is_elm_present() for later updates ELM driver - dropped changes in include/linux/platform_data/elm.h (not needed) - PATCH-3: re-ordered call to is_elm_present() for later updates ELM driver - Re-formated patch description (replaced tabs with white-spaces) Changes v3 -> v4 (Resent with CC: devicetree-discuss@xxxxxxxxxxxxxxxx) - [Patch 1/3] removed MTD_NAND_OMAP_BCH8 & MTD_NAND_OMAP_BCH4 from nand/Kconfig ECC scheme selectable via nand DT (nand-ecc-opt). - [*] rebased for l2-mtd.git Changes v2 -> v3 (Resent with Author Name fixed) - PATCH-1: re-arranged code to remove redundancy, added NAND_BUSWIDTH_AUTO - PATCH-2: updated nand-ecc-opt DT mapping and Documentation - PATCH-3: code-cleaning + changes to match PATCH-1 - PATCH-4 <DROPPED> update DT attribute for ti,nand-ecc-opt - received feedback to keep DT mapping independent of linuxism - PATCH-4:<NEW> : ARM: dts: AM33xx: updated default ECC scheme in nand-ecc-opt - independent patch for AM335x-evm.dts update based on PATCH-2 Changes v1 -> v2 added [PATCH 3/4] and [PATCH 4/4] Patches in this series: [PATCH 1/4]->[PATCH v5 2/4]: clean-up and optimization for supported ECC schemes. [PATCH 2/4]->[PATCH v5 1/4]: 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]: ARM: dts: AM33xx: updated default ECC scheme in 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.
