From 68ec9c85a9d334c7598b4972af037de05c034f8d Mon Sep 17 00:00:00 2001 From: Prabhakar Kushwaha Date: Fri, 4 Oct 2013 13:47:58 +0530 Subject: mtd: move & update nand_ecclayout structure (plus board changes) nand_ecclayout is present in mtd.h at Linux. Move this structure to mtd.h to comply with Linux. Also, increase the ecc placement locations to 640 to suport device having writesize/oobsize of 8KB/640B. This means that the maximum oobsize has gone up to 640 bytes and consequently the maximum ecc placement locations have also gone up to 640. Changes from Prabhabkar's version (squashed into one patch to preserve bisectability): - Added _LARGE to MTD_MAX_*_ENTRIES This makes the names match current Linux source, and resolves a conflict between http://patchwork.ozlabs.org/patch/280488/ and http://patchwork.ozlabs.org/patch/284513/ The former was posted first and is closer to matching Linux, but unlike Linux it does not add _LARGE to the names. The second adds _LARGE to one of the names, and depends on it in a subsequent patch (http://patchwork.ozlabs.org/patch/284512/). - Made max oobfree/eccpos configurable, and used this on tricorder, alpr, ASH405, T4160QDS, and T4240QDS (these boards failed to build for me without doing so, due to a size increase). On tricorder SPL, this saves 2576 bytes (and makes the SPL build again) versus the new default of 640 eccpos and 32 oobfree, and saves 336 bytes versus the old default of 128 eccpos and 8 oobfree.

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.
