8 bool "Enable driver model for Trusted Platform Module drivers"

10 help
11 Enable driver model for TPMs. The TIS interface (tis_open(),
12 tis_sendrecv(), etc.) is then implemented by the TPM uclass. Note
13 that even with driver model only a single TPM is currently
14 supported, since the tpm library assumes this.

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

29 This driver supports an Atmel TPM device connected on the I2C bus.
30 The usual tpm operations and the 'tpm' command can be used to talk
31 to the device using the standard TPM Interface Specification (TIS)

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