10 * This file describes the abstraction of any NAND ECC engine. It has been
11 * designed to fit most cases, including parallel NANDs and SPI-NANDs.
15 * - external: The ECC engine is outside the NAND pipeline, typically this
17 * outside the NAND controller pipeline.
18 * - pipelined: The ECC engine is inside the NAND pipeline, ie. on the
19 * controller's side. This is the case of most of the raw NAND
23 * - ondie: The ECC engine is inside the NAND pipeline, on the chip's side.
24 * Some NAND chips can correct themselves the data.
