lib: Remove inclusion from these files

2023-12-21T13:54:37+00:00

After some header file cleanups to add missing include files, remove
common.h from all files in the lib directory. This primarily means just
dropping the line but in a few cases we need to add in other header
files now.

tpm: Check outgoing command size

2021-07-15T22:42:05+00:00

In tpm_sendrecv_command() the command buffer is passed in. If a mistake is
somehow made in setting this up, the size could be out of range. Add a
sanity check for this.

tpm: Add debugging of request in tpm_sendrecv_command()

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

The response is shown but not the request. Update the code to show both
if debugging is enabled.

Use a 'uint' type for size so it matches the register-word size on both
32- and 64-bit machines.

tpm: Remove use of build-time TPM versions

2018-12-05T13:01:34+00:00

There is only one place in the code which assumes at build-time that we
are using either a v1 or a v2 TPM. Fix this up and add a new function to
return the version of a TPM.

Supported TPM versions (v1 and v2) can be enabled independently and it is
possible to use both versions at once. This is useful for sandbox when
running tests.

tpm: Convert to use a device parameter

2018-11-29T16:30:06+00:00

At present many TPM calls assume there is only one TPM in the system and
look up this TPM themselves. This is inconsistent with driver model, which
expects all driver methods to have a device parameter. Update the code to
correct this.

tpm: Tidy up logging in tpm-common.c

2018-10-09T10:40:27+00:00

At present this file uses logging but it should use the new macros. Update
it and add a log message for an error.

tpm: report driver error code to upper layer

2018-05-26T00:12:56+00:00

Instead of returning a generic 'library' error, report back the actual
error code so it can be displayed to the user by the regular error path.

tpm: add possible traces to analyze buffers returned by the TPM

2018-05-26T00:12:56+00:00

When debugging, it is welcome to get more information about what the TPM
returns. Add the possibility to print the packets received to show their
exact content.
