tpm: Require a digest source when extending the PCR

2022-09-03T13:53:58+00:00

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.

tpm: Export the TPM-version functions

2022-08-02T20:50:02+00:00

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.

doc: replace @return by Return:

2022-01-19T17:11:34+00:00

Sphinx expects Return: and not @return to indicate a return value.

find . -name '*.c' -exec \
sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \;

find . -name '*.h' -exec \
sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \;

tpm: Add an API that can support v1.2 and v2

2021-03-02T20:53:37+00:00

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.
