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.

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
