Hardware ECC
configname: CONFIG_MTD_NAND_AT91_ECC_HW
ECC management for NAND Flash / SmartMedia on AT91
└─>Hardware ECC
In linux kernel since version 2.6.26 (release Date: 2008-07-13)
Uses hardware ECC provided by the at91sam9260/at91sam9263 chip
instead of software ECC.
The hardware ECC controller is capable of single bit error
correction and 2-bit random detection per page.
NB : hardware and software ECC schemes are incompatible.
If you switch from one to another, you'll have to erase your
mtd partition.
If unsure, say Y
