Subject: [PATCH v3 0/4] mtd:nand:omap2: clean-up of supported ECC schemes
Date: Sun, 23 Jun 2013 23:28:15 +0530 [thread overview]
Message-ID: <1372010299-30141-1-git-send-email-pekon@ti.com> (raw)
(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.
