*Changes v5 - v6*
[PATCH 1/4]:
- updated DT binding for gpmc-nand based on 'Olof Johansson's
feedbacks
http://lists.infradead.org/pipermail/linux-mtd/2013-
August/048394.html
- detection of ELM device via ti,elm-id DT node, moved to gpmc.c
driver
[PATCH 2/4]
- removed: support for following obselete ECC schemes
OMAP_ECC_HAMMING_CODE_DEFAULT (S/W based 1-bit Hamming
ECC)
OMAP_ECC_HAMMING_CODE_HW_ROMCODE (H/W based 1-bit
Hamming ECC scheme)
- updated: using omap_oobinfo as chip-ecc.layout for all ecc-
schemes
- clean: error messages
[PATCH 3/4] cleaned to include changes for OMAP_ECC_BCH8_CODE_HW
only
[PATCH 4/4] updated to include DT property changes
*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-disc...@lists.ozlabs.org)
- [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_HW |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):
ARM: OMAP2+: cleaned-up DT support of various ECC schemes
mtd:nand:omap2: clean-up BCHx_HW and BCHx_SW ECC configurations in
device_probe
mtd:nand:omap2: updated support for BCH4 ECC scheme
ARM: dts: AM33xx: updated default ECC scheme in nand-ecc-opt
