This device provides a way to sign data using an internal, unique key.
It can be useful for features such as unlocking an encrypted disk.

This series provides basic support for the Tkey, with a uclass, two
sandbox drivers (emulator and serial), a simple command some tests.

  tkey: Provide a uclass for the Tillitis TKey
  tkey: Add the signer firmware
  tkey: Add emulator and test
  tkey: Add a command
  sandbox: Add TTY configuration for TKey serial communication
  tkey: Add a sandbox driver for real TKey hardware
