disabled. If a board need legacy image format support
enable this through CONFIG_IMAGE_FORMAT_LEGACY
CONFIG_FIT_DISABLE_SHA256
Supporting SHA256 hashes has quite an impact on binary size.
For constrained systems sha256 hash support can be disabled
with this option.
- Standalone program support:
CONFIG_STANDALONE_LOAD_ADDR
