config MTD_NAND_ECC_SW_HAMMING bool"Software Hamming ECC engine" default y if MTD_RAW_NAND
select MTD_NAND_ECC
help 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 thiscase BCH or RS will be
preferred.
config MTD_NAND_ECC_SW_HAMMING_SMC bool"NAND ECC Smart Media byte order"
depends on MTD_NAND_ECC_SW_HAMMING default n
help
Software ECC according to the Smart Media Specification.
The original Linux implementation had byte 0and1 swapped.
config MTD_NAND_ECC_SW_BCH bool"Software BCH ECC engine"
select BCH
select MTD_NAND_ECC default n
help 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.
