• Reworked image encryption support for Zephyr, static dummy key files are no longer in the code, a pem file must be supplied to extract the private and public keys. The Kconfig menu has changed to only show a single option for enabling encryption and selecting the key file.
• Serial recovery can now read and handle encrypted seondary slot partitions.
• Serial recovery with MBEDTLS no longer has undefined operations which led to usage faults when the secondary slot image was encrypted.
