Hello Team , Am using u-boot 2015.07 version downloaded from git I have two queries 1. Which is the file to enable secure boot config in this version for imx6q SabreSD board ? (CONFIG_SECURE_BOOT) 2. When I give the u-boot command 'hab_status' in u-boot prompt, am getting "Unknown command 'hab_status' - try 'help'" Please let me know the solution for both. -Supriya =====-----=====-----===== Notice: The information contained in this e-mail message and/or attachments to it may contain confidential or privileged information.

Hi All, This patch series add Fastboot support to TexasInstruments AM57XX EVM board and improves eMMC support. The most of code was borrowed from DRA7 EVM (since this board is very similar to DRA7 EVM). Next commands were tested: - fastboot devices - fastboot getvar - fastboot oem format - fastboot flash Sam Protsenko (6): arm: am57xx: Enable USB gadget in AM57XX arm: am57xx: Enable Fastboot arm: am57xx: Define Android partition table arm: am57xx: Set serial# variable arm: am57xx: Enable 8-bit eMMC access on AM57XX EVM arm: am57xx: Keep environment in eMMC board/ti/am57xx/board.c | 1 + include/configs/am57xx_evm.h | 58 +++++++++++++++++++++++++++++++++++++++++++----- 2 files changed, 53 insertions(+), 6 deletions(-)

[U-Boot] Eeprom Configuration
by Guy Thouret 09 Mar '16

09 Mar '16

Hello u-boot, I'm defining a new board config and have some observations about eeprom configuration I hope someone could clarify for me. There appear to be two conflicting config options: CONFIG_I2C_ENV_EEPROM_BUS and CONFIG_SYS_I2C_EEPROM_BUS What are the purpose of these two options? Could we do without CONFIG_I2C_ENV_EEPROM_BUS and just use CONFIG_SYS_I2C_EEPROM_BUS? An include for the TI SoC I am using defines CONFIG_SPI, when this is defined the following code sets CONFIG_SYS_DEF_EEPROM_ADDR to 0. CONFIG_SYS_DEF_EEPROM_ADDR is used in common/env_eeprom.c as the i2c address to read the environment from so with CONFIG_SPI set one can not use an eeprom for the u-boot environment. include/common.h:475 #if defined(CONFIG_SPI) || !defined(CONFIG_SYS_I2C_EEPROM_ADDR) # define CONFIG_SYS_DEF_EEPROM_ADDR 0 #else #if !defined(CONFIG_ENV_EEPROM_IS_ON_I2C) # define CONFIG_SYS_DEF_EEPROM_ADDR CONFIG_SYS_I2C_EEPROM_ADDR #endif #endif /* CONFIG_SPI || !defined(CONFIG_SYS_I2C_EEPROM_ADDR) */ If I accidentally define CONFIG_ENV_EEPROM_IS_ON_I2C likewise, CONFIG_SYS_DEF_EEPROM_ADDR remains unset and the environment is not read. It would seem logical to define that as my environment eeprom is indeed on an eeprom so I'm not sure why that config option exists.

[U-Boot] [PATCH V2 0/3] imx6ul: convert to enable pinctrl/DM POWER
by Peng Fan 09 Mar '16

09 Mar '16

V2: Only a small change: Use CONFIG_SPL_BUILD to comment out I2C to SPL, but not CONFIG_SPL for PATCH V2 3/3 This patch set is to covert to enable pinctrl driver and DM_PMIC and DM_REGULATOR for imx6ul 14x14/9x9 evk board. This patch set is only to add device tree for i.MX6UL and is just initial step to convert to support device tree for i.MX6/7, I just have an idea to discard the pinmux settings in board file and let pinctrl driver to handle these for different drivers. I am not very sure whether we need a full device tree here, since we do not support so many devices as linux kernel. Any comments on this? There maybe some work need to be done to support this. To the i2c part, the pinmux settings are still needed in board file, because there are some dependency in arch/arm/imx-common/i2c-mxv7.c. In future, we may need to refine this to totally let i2c driver handle this.

[U-Boot] [RFC] armv8: layerscape: Add support of u-boot device tree fix-up
by Prabhakar Kushwaha 09 Mar '16

09 Mar '16

There is a requirement of u-boot dts fix-up before it is being consumed by u-boot. NXP's SoC LS2085A, LS2080A and LS2088A are almost same except variation in ARM core where LS2085A/LS2080A has A57 and LS2088A has A72. These SoCs will be placed on common LS2085ARDB platform. So instead of maintaining defferent device tree per SoC, fix-up dts before being used by u-boot.

[U-Boot] [PATCH V2 1/2] malloc: use hidden visibility
by Stephen Warren 09 Mar '16

09 Mar '16

When running sandbox, the following phases occur, each with different malloc implementations or behaviors: 1) Dynamic linker execution, using the dynamic linker's own malloc() implementation. This is fully functional. 2) After U-Boot's malloc symbol has been hooked into the GOT, but before any U-Boot code has run. This phase is entirely non-functional, since U-Boot's gd symbol is NULL and U-Boot's initf_malloc() and mem_malloc_init() have not been called. At least on Ubuntu Xenial, the dynamic linker does make both malloc() and free() calls during this phase. Currently these free() calls crash since they dereference gd, which is NULL. U-Boot itself makes no use of malloc() during this phase. 3) U-Boot execution after gd is set and initf_malloc() has been called. This is fully functional, albeit via a very simple malloc() implementation. 4) U-Boot execution after mem_malloc_init() has been called. This is fully functional with a complete malloc() implementation. Furthermore, if code that called malloc() during phase 1 calls free() in phase 3 or later, it is likely that heap corruption will occur, since U-Boot's malloc implementation will assume the pointer is part of its own heap, although it isn't. I have not actively observed this happening. To prevent phase 2 from happening, this patch makes all of U-Boot's malloc library public symbols have hidden visibility. This prevents them from being hooked into the GOT, so only code in the U-Boot binary itself actually calls them; any other code will call into the standard C library malloc(). This also avoids the "furthermore" issue mentioned above. I have seen references to this GCC pragma in blog posts from 2008, and RHEL5's ancient gcc appears to accept it fine, so I believe it's quite safe to use it without checking gcc version.
