2013-11-21mtd: nand: omap: enable BCH ECC scheme using ELM for generic platformpekon gupta
BCH8_ECC scheme implemented in omap_gpmc.c driver has following favours +-----------------------------------+-----------------+-----------------+ |ECC Scheme | ECC Calculation | Error Detection | +-----------------------------------+-----------------+-----------------+ |OMAP_ECC_BCH8_CODE_HW |GPMC |ELM H/W engine | |OMAP_ECC_BCH8_CODE_HW_DETECTION_SW |GPMC |S/W BCH library | +-----------------------------------+-----------------+-----------------+ Current implementation limits the BCH8_CODE_HW only for AM33xx device family. (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>
2013-11-21mtd: nand: omap: make am33xx/elm.c as common driver for all OMAPx and AMxxxx ↵pekon gupta
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.

2013-11-15TI:omap: Update u-boot-spl.lds for i2c multibus/multiadapter updateTom Rini
In 6789e84 we update u-boot-spl.lds for OMAP to ensure we include adapter information, as we use i2c during SPL. However, the regex used also means we included commands that may have been built. On omap5_uevm this leads to a failure as we include the command from the do_tca642x command, and fail to link. The fix is to restrict our regex to only the i2c list parts.

Conflicts: arch/arm/cpu/arm926ejs/mxs/Makefile board/compulab/cm_t35/Makefile board/corscience/tricorder/Makefile board/ppcag/bg0900/Makefile drivers/bootcount/Makefile include/configs/omap4_common.h include/configs/pdnb3.h Makefile conflicts are due to additions/removals of object files on the ARM branch vs KBuild introduction on the main branch. Resolution consists in adjusting the list of object files in the main branch version. This also applies to two files which are not listed as conflicting but had to be modified: board/compulab/common/Makefile board/udoo/Makefile include/configs/omap4_common.h conflicts are due to the OMAP4 conversion to ti_armv7_common.h on the ARM side, and CONFIG_SYS_HZ removal on the main side. Resolution is to convert as this icludes removal of CONFIG_SYS_HZ. include/configs/pdnb3.h is due to a removal on ARM side. Trivial resolution is to remove the file. Note: 'git show' will also list two files just because they are new: include/configs/am335x_igep0033.h include/configs/omap3_igep00x0.h

2013-11-01ARM: OMAP5: DDR3: Change io settingsSRICHARAN R
The change from 0x64656465 to 0x64646464 is to remove the weak pull enabled on DQS, nDQS lines. This pulls the differential signals in the same direction which is not intended. So disabling the weak pulls improves signal integrity. On the uEVM there are 4 DDR3 devices. The VREF for 2 of the devices is powered by the OMAP's VREF_CA_OUT pins. The VREF on the other 2 devices is powered by the OMAP's VREF_DQ_OUT pins. So the net effect here is that only half of the DDR3 devices were being supplied a VREF! This was clearly a mistake. The second change improves the robustness of the interface and was specifically seen to cure corruption observed at high temperatures on some boards. With the above two changes better memory stability was observed with extended temperature ranges around 100C. Signed-off-by: Sricharan R <r.sricharan@ti.com>
2013-11-01dra7xx_evm: Enabled UART-boot mode and add dra7xx_evm_uart3 buildMinal Shah
UART booting is supported on this SoC, but via UART3 rather than UART1. Because of this we must change the board to use UART3 for all console access (only one UART is exposed on this board and a slight HW mod is required to switch UARTs).
