To OMAP3/4/5 and AM335x users, Though I have tested the following series on AM335x-EVM, but it would be good if it can also be tested on other platforms like OMAP3/4/5 custom boards which use NAND. This would be helpful, as this patch series provides base for further enhancement and cleanup of omap2-nand driver. with regards, pekon > -----Original Message----- > From: Gupta, Pekon > Sent: Sunday, June 23, 2013 11:28 PM > To: tony@xxxxxxxxxxx; artem.bityutskiy@xxxxxxxxxxxxxxx; Cousson, Benoit > Cc: arnd@xxxxxxxx; Philip, Avinash; Balbi, Felipe; linux- > mtd@xxxxxxxxxxxxxxxxxxx; linux-omap@xxxxxxxxxxxxxxx; > jp.francois@xxxxxxxxxx; Gupta, Pekon > Subject: [PATCH v3 0/4] mtd:nand:omap2: clean-up of supported ECC > schemes > > (with Author Name fixed) > Changes v2 -> v3 > - 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]: 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]: 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. > > > Pekon Gupta (4): > mtd:nand:omap2: clean-up BCHx_HW and BCHx_SW ECC configurations in > device_probe > ARM: OMAP2+: cleaned-up DT support of various ECC schemes > mtd:nand:omap2: updated support for BCH4 ECC scheme > ARM: dts: AM33xx: updated default ECC scheme in nand-ecc-opt > > .../devicetree/bindings/mtd/gpmc-nand.txt | 65 ++- > arch/arm/boot/dts/am335x-evm.dts | 2 +- > arch/arm/mach-omap2/gpmc.c | 14 +- > drivers/mtd/nand/Kconfig | 7 +- > drivers/mtd/nand/omap2.c | 482 ++++++++++----------- > include/linux/platform_data/elm.h | 4 + > include/linux/platform_data/mtd-nand-omap2.h | 22 +- > 7 files changed, 307 insertions(+), 289 deletions(-) > > -- > 1.8.1 -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
