From: Pekon Gupta Date: Tue, 18 Mar 2014 13:26:42 +0000 (+0530) Subject: mtd: nand: omap: add field to indicate current ecc-scheme in 'struct omap_nand_info' X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4e558072ef91f0ca681a74c3aef9d6a30c116f2a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git mtd: nand: omap: add field to indicate current ecc-scheme in 'struct omap_nand_info' Information of currently selected ECC scheme 'enum omap_ecc ecc_opt' should available outside platform-data, so that single nand_chip->ecc callback can support multiple ecc-scheme configurations.
