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.

Software ECC according to the Smart Media Specification.
The original Linux implementation had byte 0 and 1 swapped.

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.
