CONFIG_MTD_NAND_ECC_SW_HAMMING: Software Hamming ECC engine

General informations

The Linux kernel configuration item CONFIG_MTD_NAND_ECC_SW_HAMMING has multiple definitions:

Software Hamming ECC engine found in drivers/mtd/nand/Kconfig

The configuration item CONFIG_MTD_NAND_ECC_SW_HAMMING:

• prompt: Software Hamming ECC engine
• type: bool
• depends on: CONFIG_MTD_RAW_NAND
• defined in drivers/mtd/nand/Kconfig
• found in Linux kernels: 5.11–5.19, 6.0–6.8, 6.9-rc+HEAD
• modules built: nand_ecc

Help text

This enables support for software Hamming error correction. This correction can correct up to 1 bit error per chunk and detect up to 2 bit errors. While it used to be widely used with old parts, newer NAND chips usually require more strength correction and in this case BCH or RS will be preferred.
