Simon Glass	a557d258c6	tpm: Require a digest source when extending the PCR ... This feature is used for measured boot, so we can add a log entry to the TCPA with some information about where the digest comes from. It is not currently supported in the TPM drivers, but add it to the API so that code which expects it can signal its request.

Simon Glass	5e5937822a	tpm: Export the TPM-version functions ... These functions should really be available outside the TPM code, so that other callers can find out which version the TPM is. Rename them to have a tpm_ prefix() and add them to the header file.

Simon Glass	bfe8fa262c	tpm: Add an API that can support v1.2 and v2 ... There are two different TPM standards. U-Boot supports both but each has its own set of functions. We really need a single TPM API that can call one or the other. This is not always possible as there are some differences between the two standards, but it is mostly possible. Add an API to handle this. So far it is not plumbed into the build and only supports TPMv1.
