zephyr: Bring in the Zephyr build Add support for building mcuboot as a Zephyr application. This is copied from the iotboot repo with some minor reorganization to work with the mcuboot directory layout.
2017-01-07 02:16:53 +08:00
CONFIG_CONSOLE_HANDLER=y
zephyr: use SYS_LOG instead of printk Easier to manage and can be easily disabled via config. Signed-off-by: Ricardo Salveti <ricardo.salveti@linaro.org>

CONFIG_SYS_LOG=y

CONFIG_DEBUG=y
zephyr: disable clock before reset Avoid clock related interrupts before jumping into the first image. Safe to disable as the first application will enable the clock/timer again once booted. Signed-off-by: Ricardo Salveti <ricardo.salveti@linaro.org>

CONFIG_SYSTEM_CLOCK_DISABLE=y

CONFIG_MAIN_STACK_SIZE=10240
CONFIG_MBEDTLS=y
CONFIG_MBEDTLS_BUILTIN=y
CONFIG_MBEDTLS_CFG_FILE="config-boot.h"
Zephyr: Use mbed TLS allocator Instead of the overly-simplistic allocator in Zephyr, use the still simplistic allocator in mbed TLS. On K64f, this saves 848 bytes of text, 44 bytes of data, and 208 bytes of bss. Signed-off-by: David Brown <david.brown@linaro.org>

CONFIG_FLASH=y
zephyr: Enable MPU flash writing Recent Zephyr trees require this config option to be set in order to be able to write to the flash device. Without it, targets with an MPU enabled will abort during startup, usually before even printing a message to the UART. Signed-off-by: David Brown <david.brown@linaro.org>
2017-07-26 14:34:56 +08:00
CONFIG_MPU_ALLOW_FLASH_WRITE=y
boot/zephyr/prj.conf: disable bluetooth support by default Bluetooth is enabled by default with some boards, so just make sure that it gets disabled here to avoid having a large bootloader firmware. Signed-off-by: Ricardo Salveti <ricardo.salveti@linaro.org>
2017-01-18 21:34:47 +08:00
zephyr: disable multithreading The bootloader is just using Zephyr as a HAL and doesn't require thread scheduling. Build Zephyr in single-threaded mode and gain some footprint savings. Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>
2017-03-03 05:40:39 +08:00
CONFIG_MULTITHREADING=n
zephyr: turn off I2C Upstream Zephyr is making a habit of enabling subsystems on any board that supports them. That's a potential security risk if any of those allow interference with the running bootloader, and is currently exceeding mcuboot's flash allowance on some STM32 targets, e.g. 96b_carbon. Turn off I2C to restore the build for those. Signed-off-by: Marti Bolivar <marti.bolivar@linaro.org>
