12  * Here is a partial implementation of TPM commands.  Please consult TCG Main
13  * Specification for definitions of TPM commands.
96  * TPM return codes as defined in the TCG Main specification
97  * (TPM Main Part 2 Structures; Specification version 1.2)
103 	/* TPM-defined fatal error codes */
202 	/* TPM-defined non-fatal errors */
233 /* Max buffer size supported by our tpm */
237  * struct tpm_chip_priv - Information about a TPM, stored by the uclass
253  * struct tpm_ops - low-level TPM operations
262  * This interface is for low-level TPM access. It does not understand the
263  * concept of localities or the various TPM messages. That interface is
291 	 * get_desc() - Get a text description of the TPM
301 	 * send() - send data to the TPM
313 	 * recv() - receive a response from the TPM
319 	 * Returns number of bytes received on success, -EAGAIN if the TPM
328 	 * This is called if receiving times out. The TPM may need to abort
337 	 * xfer() - send data to the TPM and get response
341 	 * TPM communication for a single transfer.
377  * tpm_get_desc() - Get a text description of the TPM
387  * tpm_xfer() - send data to the TPM and get response
411  * Initialize TPM device.  It must be called before any TPM commands.
420  * @param mode		TPM startup mode
498  * Issue a TSC_PhysicalPresence command.  TPM physical presence flag
501  * @param presence	TPM physical presence flag
618  * Get the TPM permanent flags value
626  * Get the TPM permissions
634  * Flush a resource with a given handle and type from the TPM
649  * @return 0 if key was found in TPM; != 0 if not.
