This controller +can be used to support both SLC and MLC NAND Flash devices. It supports to +generate ECC to correct 2, 4, 8, 12 or 24 bits of error per sector (512 or +1024 bytes) of data. + +Following Atmel AT91 products support PMECC. +- AT91SAM9X25, X35, G25, G15, G35 (tested) +- AT91SAM9N12 (not tested, Should work) + +As soon as your nand flash software ECC works, you can enable PMECC. + +To use PMECC in this driver, the user needs to set: + 1. the PMECC correction error bits capability: CONFIG_PMECC_CAP. + It can be 2, 4, 8, 12 or 24. + 2. The PMECC sector size: CONFIG_PMECC_SECTOR_SIZE. + It only can be 512 or 1024. + 3.
