arm-trusted-firmware - 2.10.0+dfsg-1+b2 main

The "secure world" on arm64 machines is a special level of CPU
privilege that is hidden from the normal OS, and has complete
control over the system. It provides both initialization during
early boot stages (before u-boot or EFI) and system monitor
functionality once the machine is booted up.
