Dominik Ermel 35bf48c5b7 boot: Change boot_enc_load to take slot number instead of image 
In all cases where boot_enc_load is called it is known what slot
is addressed, so it is better to just pass the slot number
instead of making the boot_enc_load figure out slot number from
image index and provided flash area object.

MCUboot

Package on PyPI Coverity Scan Build Status Build Status (Sim) Build Status (Mynewt) Build Status (Espressif) Publishing Status (imgtool) Build Status (Travis CI) Apache 2.0

This is MCUboot version 2.1.0

MCUboot is a secure bootloader for 32-bits microcontrollers. It defines a common infrastructure for the bootloader and the system flash layout on microcontroller systems, and provides a secure bootloader that enables easy software upgrade.

MCUboot is not dependent on any specific operating system and hardware and relies on hardware porting layers from the operating system it works with. Currently, MCUboot works with the following operating systems and SoCs:

RIOT is supported only as a boot target. We will accept any new port contributed by the community once it is good enough.

MCUboot How-tos

See the following pages for instructions on using MCUboot with different operating systems and SoCs:

There are also instructions for the Simulator.

Roadmap

The issues being planned and worked on are tracked using GitHub issues. To give your input, visit MCUboot GitHub Issues.
