This library is charged with:
- decrypting firmware radio images during recovery update
- preventing device boot break on main/backup bootloaders update failure
Those features are implemented by registering device specific updater
script commands used by update mechanism. The library is statically
linked to Android updater executable during Android build. The commands
implemented in the library will be called by updater-script during OTA
update.
