CONFIG_MTD_NAND_OMAP_BCH: Support hardware based BCH error correction

General informations

The Linux kernel configuration item CONFIG_MTD_NAND_OMAP_BCH has multiple definitions:

Enable support for hardware BCH error correction found in drivers/mtd/nand/Kconfig

The configuration item CONFIG_MTD_NAND_OMAP_BCH:

Help text

Support for hardware BCH error correction.

Enable support for hardware BCH error correction found in drivers/mtd/nand/Kconfig

The configuration item CONFIG_MTD_NAND_OMAP_BCH:

Support for hardware BCH error correction.

Support hardware based BCH error correction found in drivers/mtd/nand/Kconfig

The configuration item CONFIG_MTD_NAND_OMAP_BCH:

Help text

This config enables the ELM hardware engine, which can be used to locate and correct errors when using BCH ECC scheme. This offloads the cpu from doing ECC error searching and correction. However some legacy OMAP families like OMAP2xxx, OMAP3xxx do not have ELM engine so this is optional for them.
