- Add image security counter verification (read security counter value
from the image manifest and compare it against the stored/active
security counter) as an optional part of the image validation process
to prevent the restoration of older, potentially vulnerable images.
- This feature can be enabled with the MCUBOOT_HW_ROLLBACK_PROT option.
- Add security counter interface to MCUBoot. If HW rollback protection
is enabled then the platform must provide a mechanism to store and
read the security counter value in a robust and secure way.
