| * | mtd: nand: omap: add CONFIG_NAND_OMAP_ECCSCHEME for selection of ecc-schemepekon gupta2013-11-2117-15/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

(using CONFIG_AM33XX). However, other SoC families (like TI81xx) also have ELM hardware module, and can support ECC error detection using ELM. This patch - removes CONFIG_AM33xx Thus this driver can be reused by all devices having ELM h/w engine. - adds omap_select_ecc_scheme() A common function to handle ecc-scheme related configurations. This can be used both during device-probe and via user-space u-boot commads to change ecc-scheme. During device probe ecc-scheme is selected based on CONFIG_NAND_OMAP_ELM or CONFIG_NAND_OMAP_BCH8 - enables CONFIG_BCH S/W library (lib/bch.c) required by OMAP_ECC_BCHx_CODE_HW_DETECTION_SW is enabled by CONFIG_BCH. - enables CONFIG_SYS_NAND_ONFI_DETECTION for auto-detection of ONFI compliant NAND devices - updates following README doc doc/README.nand board/ti/am335x/README doc/README.omap3 Signed-off-by: Pekon Gupta <pekon@ti.com> [scottwood@freescale.com: fixed unused variable warning] Signed-off-by: Scott Wood <scottwood@freescale.com>
| * | mtd: nand: omap: make am33xx/elm.c as common driver for all OMAPx and AMxxxx ↵pekon gupta2013-11-219-5/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | platforms ELM hardware engine which is used for ECC error detection, is present on all latest OMAP SoC (like OMAP4xxx, OMAP5xxx, DRA7xxx, AM33xx, AM43xx). Thus ELM driver should be moved to common drivers/mtd/nand/ folder so that all SoC having on-chip ELM hardware engine can re-use it. This patch has following changes: - mv arch/arm/include/asm/arch-am33xx/elm.h arch/arm/include/asm/omap_elm.h - mv arch/arm/cpu/armv7/am33xx/elm.c drivers/mtd/nand/omap_elm.c - update Makefiles - update #include <asm/elm.h> - add CONFIG_NAND_OMAP_ELM to compile driver/mtd/nand/omap_elm.c and include in all board configs using AM33xx SoC platform.

| * | mtd: move & update nand_ecclayout structure (plus board changes)Prabhakar Kushwaha2013-11-219-17/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | driver/mtd/ifc: Read Status while programming NAND flashPrabhakar Kushwaha2013-11-131-5/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | as per controller description, "While programming a NAND flash, status read should never skipped. Because it may happen that a new command is issued to the NAND Flash, even when the device has not yet finished processing the previous request. This may result in unpredictable behaviour." IFC controller never polls for R/B signal after command send. It just return control to software. This behaviour may not occur with NAND flash access. because new commands are sent after polling R/B signal. But it may happen in scenario where GPCM-ASIC and NAND flash device are working simultaneously.

This can be achieved by: ./tools/buildman/buildman -b mainline_dev tegra20 However, when the SoC is a member of a family of SoCs, and each SoC has a different name, it would be even more useful to build all boards for every SoC in that family. This currently isn't possible since buildman's board selection command-line arguments are compared to board definitions using pure string equality. To enable this, compare using a regex match instead. This matches MAKEALL's handling of command-line arguments. This enables: (all Tegra) ./tools/buildman/buildman -b mainline_dev tegra (all Tegra) ./tools/buildman/buildman -b mainline_dev '^tegra.*$' (all Tegra20, Tegra30 boards, but not Tegra114) ./tools/buildman/buildman -b mainline_dev 'tegra[23]' Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Simon Glass <sjg@chromium.org>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The physical base address of the NOR flash is 0x1e000000 on the Malta boards. The hardware also maps the first 4MiB of the flash into the 0x1fc00000-0x1fffffff range. Currently, U-Boot uses the mapped address to access the flash, which does not work in recent qemu versions. Since commit a427338b222b43197c2776cbc996936df0302f51 (mips_malta: correct reading MIPS revision at 0x1fc00010) writing to the mapped address space causes a CPU exception. Due to the exception, U-Boot hangs during boot when it tries to detect the CFI flash chip. Use the correct physical address for the MALTA_FLASH_BASE constant to fix the problem. In order to avoid relocation problems, also update the CONFIG_SYS_{TEXT,MONITOR}_BASE constants. The change makes it possible to start U-Boot on a Malta board emulated with Qemu 1.6.1 and 1.7.0-rc0. It also works on older versions (tested with 1.1.1, 1.2.2, 1.4.2, 1.5.3).
