2018-11-18Kbuild: add LDFLAGS_STANDALONEDaniel Schwierzeck7-10/+14
Introduce a new Makefile variable for passing LDFLAGS to standalone programs. Currently the variable CONFIG_STANDALONE_LOAD_ADDR is misued on some archs to pass a specific linker script.

2018-11-18mips: mt76xx: linkit-smart-7688: Misc updates to dts/config/defconfigStefan Roese4-16/+31
These misc updates include the following changes: - Change baudrate from 57600 to 115200 - Enable MIPS_BOOT_CMDLINE_LEGACY - Enable FIT support - Enable ethernet support - Enable SPI support - Enable GPIO support - Change max image size from 0x40000 to 0x80000 A note about the baudrate change: The original Mediatek U-Boot version used 57600 baud. Lets move to a more common and faster speed of 115200 baud. And remove the "console=" property from the DT as its not needed.

2018-11-16fdt_region: Ensure that depth never goes below -1Konrad Beckmann1-0/+3
A specially crafted FIT image makes it possible to overflow the stack with controlled values when using the verified boot feature. Depending on the memory layout, this could be used to overwrite configuration variables on the heap and setting them to 0, e.g. disable signature verification, thus bypassing it. This change fixes a bug in fdt_find_regions where the fdt structure is parsed. A lower value than -1 of depth can lead to a buffer underflow write on the stack.

2018-11-16image-sig: Ensure that hashed-nodes is null-terminatedKonrad Beckmann1-0/+5
A specially crafted FIT image leads to memory corruption in the stack when using the verified boot feature. The function fit_config_check_sig has a logic error that makes it possible to write past the end of the stack allocated array node_inc. This could potentially be used to bypass the signature check when using verified boot. This change ensures that the number of strings is correct when counted.

2018-11-16Ability to modify distro boot filenameMartyn Welch1-3/+4
Add in the ability to modify the distro boot filename. Whilst not immediately useful in normal usage, it allows an alternative configuration to be provided when other u-boot functionality is used, such as bootcount limit, to fallback to an alternative boot configuration. In this case we can follow the same boot path as for normal boot, just using an alternatively named configuration file. For example, by providing the following `altbootcmd` when bootcount is in use: altbootcmd=setenv boot_extlinx_conf extlinux-rollback.conf; \ run distro_bootcmd Signed-off-by: Martyn Welch <martyn.welch@collabora.co.uk> Reviewed-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

2018-11-16pinctrl: stm32: Add get_pins_count() opsPatrice Chotard1-5/+85
Add get_pins_count ops to obtain the number of pins owns by a pin-controller. On STM32 SoCs bindings, each pin-controller owns several gpio banks. Each GPIO bank can own up to 16 pins. To obtain the total pins count, walk through each sub-nodes (ie GPIO banks) and sum each GPIO banks pins number. For that in probe() we build a list with each GPIO device reference found. This list will also be used with future get_pin_muxing and get_pin_name ops to speed up and optimize walk through all GPIO banks. As this code is common to all STM32 SoCs, this code is put under SPL_BUILD compilation flag to avoid to increase SPL code size for STM32F7 which is limited to 32Ko.
