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

  19         help
  20           This driver supports an Atmel TPM device connected on the I2C bus.
  21           The usual tpm operations and the 'tpm' command can be used to talk
  22           to the device using the standard TPM Interface Specification (TIS)
  23           protocol

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

  62           Enable support for authorised (AUTH1) commands as specified in the
  63           TCG Main Specification 1.2. OIAP-authorised versions of the commands
  64           TPM_LoadKey2 and TPM_GetPubKey are provided. Both features are
  65           available using the 'tpm' command, too.
