[U-Boot] [PATCH] mmc: fix OCR Polling
by Peng Fan 05 May '15

05 May '15

If in mmc_send_op_cond, OCR_BUSY is set in CMD1's response, then state is transfered to Ready state, and there is no need to send CMD1 again. Otherwise following CMD1 will recieve no response, or timeour error from driver such as fsl_esdhc.c. If not into Ready state in previous CMD1, then continue CMD1 command. In mmc_complete_op_cond, we use the value mmc->op_cond_response from mmc_send_op_cond, since there should be no CMD1 command between mmc_send_op_cond and mmc_complete_op_cond Before fixing this, uboot log shows: " CMD_SEND:0 ARG 0x00000000 MMC_RSP_NONE CMD_SEND:8 ARG 0x000001AA MMC_RSP_R1,5,6,7 0x18EC1504 CMD_SEND:55 ARG 0x00000000 MMC_RSP_R1,5,6,7 0x18EC1504 CMD_SEND:0 ARG 0x00000000 MMC_RSP_NONE CMD_SEND:1 ARG 0x00000000 MMC_RSP_R3,4 0x00FF8080 CMD_SEND:1 ARG 0x40300000 MMC_RSP_R3,4 0xC0FF8080 --> Already OCR_BUSY set CMD_SEND:1 ARG 0x40300000 MMC_RSP_R3,4 0x0096850A --> Failed CMD1 MMC init failed " Using this patch, this issue is fixed, emmc can be detected correctly.

[U-Boot] Debugging U-Boot on iMX6 with BDI3000
by Armand Ciejak 05 May '15

05 May '15

Hello, I'm trying to debug U-Boot (version: imx_v2014.04_3.14.28_1.0.0_ga) for a custom board with a BDI3000. So far I can connect to the target and I see the U-Boot code at the correct location, but after reset the PC is at 0x1ffa870c which is somewhere outside of U-Boot. Here the state after powering up th board with the BDI attached: IMX6#0>info Core number : 0 Core state : debug mode (ARM) Debug entry cause : Debug Request Current PC : 0x1ffa870c Current CPSR : 0x600001d3 (Supervisor) I need to debug from the very first assembler instruction which gets loaded at address 0x17800000 but I don't know how to configure the BDI to achieve this. Does someone would have a BDI configuration file to share? Armand

[U-Boot] [RESEND PATCH v3 00/13] Add Marvell Armada A38x 88F6820 SoC support
by Stefan Roese 05 May '15

05 May '15

This patch series adds support for the Marvell Armada A38x SoC's. Specifically the 88F6820 / 88F6828. Basic support for the DB-88F6820-GP evaluation board is added. Supporting the following interfaces: - UART - SPI (including SPI NOR flash) - I2C - Ethernet (neta) One big part of this new SoC support is the move of the already exisiting Armada XP support into the "mach-mvebu" directory. With this move its easier to re-use this code for the A38x, which is pretty similar to the AXP. Thanks, Stefan Changes in v3: - Removed coherency feature as its not used in U-Boot at all as pointed out by Thomas Petazzoni - Changed CONFIG_I2C_MVTWSI_BASE to CONFIG_I2C_MVTWSI_BASE0 for updates in mvtwsi I2C driver - Added Tested-by from Dirk and Kevin Changes in v2: - Made mvebu_soc_family() globally available so that it can be called from mbus.c - Add PL310 L2 cache base address - Update to 256KiB env sector as required for M25P128 - Add I2C IO expander initialization (fan etc) - Enable PL310 L2 cache as this is needed for correct caching OPs Stefan Roese (13): arm: armada-xp: Move SoC sources to mach-mvebu arm: armada-xp: Move SoC headers to mach-mvebu/include/mach arm: mvebu: Move mvebu-common into mach-mvebu arm: mvebu: Change header macros from ARMADA_XP to MVEBU arm: mvebu: Remove unreferenced define arm: mvebu: Only define MV88F78X60 for Armada XP arm: mvebu: Move CONFIG_SPL_LDSCRIPT to common header arm: mvebu: Add basic Armada 38x support arm: mvebu: Change network init code to allow a more flexible setup arm: mvebu: Remove coherency configuration arm: mvebu: mv-common.h: Add CONFIG_PREBOOT arm: mvebu: Add d-cache invalidate before enabling the d-cache arm: mvebu: Add Armada A38x DB-88F6820-GP board support arch/arm/Kconfig | 6 ++ arch/arm/Makefile | 5 +- arch/arm/cpu/armv7/Makefile | 1 - arch/arm/cpu/armv7/armada-xp/Makefile | 9 -- arch/arm/mach-mvebu/Makefile | 24 +++++ arch/arm/{cpu/armv7/armada-xp => mach-mvebu}/cpu.c | 96 +++++++++++++++---- arch/arm/{mvebu-common => mach-mvebu}/dram.c | 0 arch/arm/{mvebu-common => mach-mvebu}/gpio.c | 0 .../include/mach}/config.h | 15 ++- .../include/mach}/cpu.h | 13 ++- .../include/mach}/soc.h | 20 ++-- .../armv7/armada-xp => mach-mvebu}/lowlevel_spl.S | 0 arch/arm/{mvebu-common => mach-mvebu}/mbus.c | 3 - .../{mvebu-common => mach-mvebu}/serdes/Makefile | 0 .../serdes/board_env_spec.h | 0 .../serdes/high_speed_env_lib.c | 0 .../serdes/high_speed_env_spec.c | 0 .../serdes/high_speed_env_spec.h | 0 arch/arm/{cpu/armv7/armada-xp => mach-mvebu}/spl.c | 0 arch/arm/{mvebu-common => mach-mvebu}/timer.c | 0 .../{mvebu-common => mach-mvebu}/u-boot-spl.lds | 0 board/Marvell/db-88f6820-gp/Kconfig | 15 +++ board/Marvell/db-88f6820-gp/Makefile | 7 ++ board/Marvell/db-88f6820-gp/binary.0 | 16 ++++ board/Marvell/db-88f6820-gp/db-88f6820-gp.c | 103 +++++++++++++++++++++ board/Marvell/db-88f6820-gp/kwbimage.cfg | 12 +++ board/Marvell/db-mv784mp-gp/Kconfig | 2 +- board/Marvell/db-mv784mp-gp/db-mv784mp-gp.c | 3 +- board/maxbcm/Kconfig | 2 +- board/maxbcm/maxbcm.c | 2 +- configs/db-88f6820-gp_defconfig | 2 + include/configs/db-88f6820-gp.h | 72 ++++++++++++++ include/configs/db-mv784mp-gp.h | 3 +- include/configs/maxbcm.h | 3 +- include/configs/mv-common.h | 1 + 35 files changed, 378 insertions(+), 57 deletions(-) delete mode 100644 arch/arm/cpu/armv7/armada-xp/Makefile create mode 100644 arch/arm/mach-mvebu/Makefile rename arch/arm/{cpu/armv7/armada-xp => mach-mvebu}/cpu.c (71%) rename arch/arm/{mvebu-common => mach-mvebu}/dram.c (100%) rename arch/arm/{mvebu-common => mach-mvebu}/gpio.c (100%) rename arch/arm/{include/asm/arch-armada-xp => mach-mvebu/include/mach}/config.h (86%) rename arch/arm/{include/asm/arch-armada-xp => mach-mvebu/include/mach}/cpu.h (93%) rename arch/arm/{include/asm/arch-armada-xp => mach-mvebu/include/mach}/soc.h (81%) rename arch/arm/{cpu/armv7/armada-xp => mach-mvebu}/lowlevel_spl.S (100%) rename arch/arm/{mvebu-common => mach-mvebu}/mbus.c (99%) rename arch/arm/{mvebu-common => mach-mvebu}/serdes/Makefile (100%) rename arch/arm/{mvebu-common => mach-mvebu}/serdes/board_env_spec.h (100%) rename arch/arm/{mvebu-common => mach-mvebu}/serdes/high_speed_env_lib.c (100%) rename arch/arm/{mvebu-common => mach-mvebu}/serdes/high_speed_env_spec.c (100%) rename arch/arm/{mvebu-common => mach-mvebu}/serdes/high_speed_env_spec.h (100%) rename arch/arm/{cpu/armv7/armada-xp => mach-mvebu}/spl.c (100%) rename arch/arm/{mvebu-common => mach-mvebu}/timer.c (100%) rename arch/arm/{mvebu-common => mach-mvebu}/u-boot-spl.lds (100%) create mode 100644 board/Marvell/db-88f6820-gp/Kconfig create mode 100644 board/Marvell/db-88f6820-gp/Makefile create mode 100644 board/Marvell/db-88f6820-gp/binary.0 create mode 100644 board/Marvell/db-88f6820-gp/db-88f6820-gp.c create mode 100644 board/Marvell/db-88f6820-gp/kwbimage.cfg create mode 100644 configs/db-88f6820-gp_defconfig create mode 100644 include/configs/db-88f6820-gp.h -- 2.3.6

This series contains a hodge-podge of minor fixes and improvements in various areas. They were found while adjusting mainline Nyan-big to work with Chrome OS verified boot. Rather than send a large number of individual patches I decide to collect them into a series. They should all be independent so can be applied without coordination. Sample of areas covered: - Detect a USB device being connected/disconnected - TPM support with CONFIG_DM_I2C - Detect when U-Boot is started from SPL - ARM binary output and boot tweaks - Small LCD BMP-drawing improvement - Tegra removable MMC support - Various small nits in driver model, sandbox, etc. Simon Glass (23): dm: usb: Implement usb_detect_change() for driver model bootstage: Add IDs for SPI flash reading and decompression dm: i2c: Implement 'i2c bus' command for driver model dm: i2c: Add a function to find out the chip offset length tpm: Support using driver model with I2C tpm: Rename Infineon TPM to slb9645tt dm: gpio: Fix comment typo in GPIOD_IS_IN arm: Include the .got section in the binary arm: Add a prototype for save_boot_params_ret() arm: spl: Enable detecting when U-Boot is started from SPL arm: Allow cleanup_before_linux() without disabling caches sandbox: Add an implementation for cleanup_before_linux_select() sandbox: Correct error handling in state_read_file() sandbox: Add missing errno.h includes in a few files sandbox: cros_ec: Support EC_CMD_ENTERING_MODE emulation sandbox: spi: Add newline to printf() in sandbox_sf_probe sandbox: Fix warning in display_options sandbox: Support wide-screen LCD emulation lcd: Support colour lookup table on 16bpp display in BMP images tegra124: Implement spl_was_boot_source() tegra: nyan-big: Allow TPM on I2C tegra: mmc: Set the removable flag correctly tegra124: Expand SPL space by 8KB Vincent Palatin (1): usb: add device connection/disconnection detection arch/arm/config.mk | 3 +- arch/arm/cpu/armv7/cpu.c | 47 +++++---- arch/arm/dts/exynos5420-peach-pit.dts | 2 +- arch/arm/dts/exynos5800-peach-pi.dts | 2 +- arch/arm/include/asm/system.h | 16 +++ arch/arm/mach-tegra/board.c | 16 +++ arch/sandbox/cpu/cpu.c | 5 + arch/sandbox/cpu/start.c | 1 + arch/sandbox/cpu/state.c | 2 +- arch/sandbox/dts/sandbox.dts | 4 +- board/nvidia/nyan-big/pinmux-config-nyan-big.h | 4 +- common/cmd_i2c.c | 63 ++++++++++-- common/lcd.c | 23 ++++- common/usb.c | 26 +++++ common/usb_hub.c | 2 +- drivers/i2c/i2c-uclass.c | 7 ++ drivers/misc/cros_ec_sandbox.c | 2 + drivers/misc/i2c_eeprom_emul.c | 1 + drivers/misc/swap_case.c | 1 + drivers/mmc/tegra_mmc.c | 12 ++- drivers/mtd/spi/sandbox.c | 2 +- drivers/tpm/tpm.c | 89 +++++++++++++--- drivers/tpm/tpm_private.h | 3 + drivers/tpm/tpm_tis_i2c.c | 134 +++++++++++++++++-------- drivers/usb/host/usb-uclass.c | 43 ++++++++ include/asm-generic/gpio.h | 2 +- include/bmp_layout.h | 4 +- include/bootstage.h | 2 + include/common.h | 15 +++ include/configs/tegra124-common.h | 2 +- include/ec_commands.h | 15 +++ include/i2c.h | 9 +- include/spl.h | 13 +++ include/usb.h | 2 + lib/display_options.c | 2 +- lib/fdtdec.c | 2 +- 36 files changed, 472 insertions(+), 106 deletions(-) -- 2.2.0.rc0.207.ga3a616c
