boot: zephyr: fix flash page layout hacks

Zephyr now has proper page layout APIs in its flash driver. Use these
to implement flash_area_get_sectors() and flash_area_to_sectors() when
they are available. Leave the existing implementation behind as a
"legacy" version, for flash drivers which lack page layout support.

This lets us obtain all the target support we need for nRF and STM32
targets entirely from the operating system.

There are two cases where OS-level support is still not enough:

- NXP K6x targets still need an SoC family header, because their flash
  driver does not yet support CONFIG_FLASH_PAGE_LAYOUT.

- The arduino_101 target needs partition and flash alignment
  definitions in its DTS, and a flash driver with page layout support
  as well, so its board-specific header must remain for now.

Fixing these is left to future work. Once that is done,
boot/zephyr/targets/ can be removed completely.

mcuboot

Coverity Scan Build Status Build/Test

This is mcuboot, version 1.0.0

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.

Roadmap

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

Browsing

Information and documentation on the bootloader is stored within the source, and on confluence:

https://runtimeco.atlassian.net/wiki/discover/all-updates

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
