[redhat] New configs in drivers/mtd

CKI ARK Bot requested to merge configs/2020-12-18/drivers/mtd into os-build

Hi,

As part of the ongoing rebase effort, the following configuration options need to be reviewed.

As a reminder, the ARK configuration flow involves moving unreviewed configuration options from the pending directory to the ark directory. In the diff below, options are removed from the pending directory and added to the ark hierarchy. The final options that need to be ACKed are the files that are being added to the ark hierarchy.

If the value for a file that is added should be changed, please reply with a better option.

CONFIG_MTD_NAND_ECC_SW_BCH:

This enables support for software BCH error correction. Binary BCH codes are more powerful and cpu intensive than traditional Hamming ECC codes. They are used with NAND devices requiring more than 1 bit of error correction.

Symbol: MTD_NAND_ECC_SW_BCH [=n] Type : bool Defined at drivers/mtd/nand/Kconfig:38 Prompt: Software BCH ECC engine Depends on: MTD [=m] Location: -> Device Drivers -> Memory Technology Device (MTD) support (MTD [=m]) -> NAND -> ECC engine support Selects: BCH [=n] && MTD_NAND_ECC [=n]

CONFIG_MTD_NAND_ECC_SW_HAMMING:

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.

Symbol: MTD_NAND_ECC_SW_HAMMING [=n] Type : bool Defined at drivers/mtd/nand/Kconfig:18 Prompt: Software Hamming ECC engine Depends on: MTD [=m] Location: -> Device Drivers -> Memory Technology Device (MTD) support (MTD [=m]) -> NAND -> ECC engine support Selects: MTD_NAND_ECC [=n] Selected by [n]:

  • SM_FTL [=n] && MTD [=m] && BLOCK [=y]
  • MTD_NAND_NDFC [=n] && MTD [=m] && MTD_RAW_NAND [=n] && 4xx
