+ help
+ This driver emulates a TPMv1.x, 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.

+ depends on TPM_TIS_INFINEON
+ help
+ 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.
