From c66d039197e42af8867e5d0d9b904daf0fb9e6bc Mon Sep 17 00:00:00 2001 From: Pekon Gupta Date: Thu, 24 Oct 2013 18:20:18 +0530 Subject: mtd: nand: omap: combine different flavours of 1-bit hamming ecc schemes OMAP NAND driver currently supports multiple flavours of 1-bit Hamming ecc-scheme, like: - OMAP_ECC_HAMMING_CODE_DEFAULT 1-bit hamming ecc code using software library - OMAP_ECC_HAMMING_CODE_HW 1-bit hamming ecc-code using GPMC h/w engine - OMAP_ECC_HAMMING_CODE_HW_ROMCODE 1-bit hamming ecc-code using GPMC h/w engin with ecc-layout compatible to ROM code. This patch combines above multiple ecc-schemes into single implementation: - OMAP_ECC_HAM1_CODE_HW 1-bit hamming ecc-code using GPMC h/w engine with ROM-code compatible ecc-layout.
