mtd: nand: omap: add CONFIG_NAND_OMAP_ECCSCHEME for selection of ecc-scheme This patch adds new CONFIG_NAND_OMAP_ECCSCHEME, replacing other distributed CONFIG_xx used for selecting NAND ecc-schemes. This patch aims at solving following issues. 1) Currently ecc-scheme is tied to SoC platform, which prevents user to select other ecc-schemes also supported in hardware. like; - most of OMAP3 SoC platforms use only 1-bit Hamming ecc-scheme, inspite the fact that they can use higher ecc-schemes like 8-bit ecc-schemes with software based error detection (OMAP_ECC_BCH4_CODE_HW_DETECTION_SW). - most of AM33xx SoC plaforms use 8-bit BCH ecc-scheme for now, but hardware supports BCH16 ecc-scheme also. 2) Different platforms use different CONFIG_xx to select ecc-schemes, which adds confusion for user while migrating platforms. - *CONFIG_NAND_OMAP_ELM* which enables ELM hardware engine, selects only 8-bit BCH ecc-scheme with h/w based error-correction (OMAP_ECC_BCH8_CODE_HW) whereas ELM hardware engine supports other ecc-schemes also like; BCH4, and BCH16 (in future). - *CONFIG_NAND_OMAP_BCH8* selects 8-bit BCH ecc-scheme with s/w based error correction (OMAP_ECC_BCH8_CODE_HW_DETECTION_SW). - *CONFIG_SPL_NAND_SOFTECC* selects 1-bit Hamming ecc-scheme using s/w library Thus adding new *CONFIG_NAND_OMAP_ECCSCHEME* de-couples ecc-scheme dependency on SoC platform and NAND driver. And user can select ecc-scheme independently foreach board. However, selection some hardware based ecc-schemes (OMAP_ECC_BCHx_CODE_HW) still depends on presence of ELM hardware engine on SoC.
