- This driver emulates a TPM, providing access to base functions
- such as reading and writing TPM private data. This is enough to
- support Chrome OS verified boot. Extend functionality is not
- implemented.

- Some broken TPMs have a limitation on the number of bytes they can
- receive in one message. Enable this option to allow you to set this
- option. The can allow a broken TPM to be used by splitting messages
- into separate pieces.
