![]() This patch add support for BCH16_ECC to omap_gpmc driver. *need to BCH16 ECC scheme* With newer SLC Flash technologies and MLC NAND, and large densities, pagesizes Flash devices have become more suspectible to bit-flips. Thus stronger ECC schemes are required for protecting the data. But stronger ECC schemes have come with larger-sized ECC syndromes which require more space in OOB/Spare. This puts constrains like; (a) BCH16_ECC can correct 16 bit-flips per 512Bytes of data. (b) BCH16_ECC generates 26-bytes of ECC syndrome / 512B. Due to (b) this scheme can only be used with NAND devices which have enough OOB to satisfy following equation: OOBsize per page >= 26 * (page-size / 512) Signed-off-by: Pekon Gupta <pekon@ti.com> |
