zephyr: enable MULTITHREADING by default except on nRF

CONFIG_MULTITHREADING is generally assumed to be y by the zephyr
kernel, even though that's not reflected in the Kconfig. For example,
semaphores depend on it being y, but CMake will still build sem.c even
if it's n.

The sensible default for this option is thus y.

However, it's a size advantage to disable it if the platform drivers
are all aware of this option, such as nRF.

Let's re-work our use of this option to keep it disabled when we know
it's safe, but enable it by default so more platforms can be expected
to work out of the box.

mcuboot

Coverity Scan Build Status Build/Test

This is mcuboot, version 1.3.1

MCUboot is a secure bootloader for 32-bit MCUs. The goal of MCUboot is to define a common infrastructure for the bootloader, system flash layout on microcontroller systems, and to provide a secure bootloader that enables easy software upgrade.

MCUboot is operating system and hardware independent and relies on hardware porting layers from the operating system it works with. Currently, mcuboot works with both the Apache Mynewt, and Zephyr operating systems, but more ports are planned in the future. RIOT is currently supported as a boot target with a complete port planned.

Using MCUboot

Instructions for different operating systems can be found here:

Roadmap

The issues being planned and worked on are tracked using GitHub issues. To participate please visit:

MCUBoot GitHub Issues

Issues were previously tracked on MCUboot JIRA , but it is now deprecated.

Browsing

Information and documentation on the bootloader are stored within the source.

It was previously also documented on confluence: MCUBoot Confluence however, it is now deprecated and not currently maintained

For more information in the source, here are some pointers:

  • boot/bootutil: The core of the bootloader itself.
  • boot/boot_serial: Support for serial upgrade within the bootloader itself.
  • boot/zephyr: Port of the bootloader to Zephyr
  • boot/mynewt: Mynewt bootloader app
  • imgtool: A tool to securely sign firmware images for booting by mcuboot.
  • sim: A bootloader simulator for testing and regression
