Remove current_image global and macro updates

Currently to determine which image is being operated on, there is a global
variable called current_image which is used by most macros and APIs to
correctly access the flash areas required by the bootloader. This moves
this variable to the already existing state struct and refactors all
macros and APIs to receive the current image by parameters. To maintain
compatibility some of the macros were not updated and use image 0 when
called.

The definitions of FLASH_AREA_IMAGE_PRIMARY and FLASH_AREA_IMAGE_SECONDARY
for Mynewt compatibility were moved out of bootutil sources to a Mynewt
specific include file.

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
