2018-12-05tpm: Fix a logging warning in unpack_byte_string()Simon Glass
Fix the printf() string to avoid a warning. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-12-05tpm: Remove use of build-time TPM versionsSimon Glass
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.

2018-11-29tpm: Convert to use a device parameterSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09tpm: Tidy up logging in tpm-common.cSimon Glass
At present this file uses logging but it should use the new macros. Update it and add a log message for an error. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-05-25tpm: report driver error code to upper layerMiquel Raynal
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. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Reviewed-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
2018-05-25tpm: add possible traces to analyze buffers returned by the TPMMiquel Raynal
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.

2018-05-25tpm: disociate TPMv1.x specific and generic codeMiquel Raynal
There are no changes in this commit but a new organization of the code as follow. * cmd/ directory: > move existing code from cmd/tpm.c in cmd/tpm-common.c > move specific code in cmd/tpm-v1.c > create a specific header file with generic definitions for commands only called cmd/tpm-user-utils.h * lib/ directory: > move existing code from lib/tpm.c in lib/tpm-common.c > move specific code in lib/tpm-v1.c > create a specific header file with generic definitions for the library itself called lib/tpm-utils.h * include/ directory: > move existing code from include/tpm.h in include/tpm-common.h > move specific code in include/tpm-v1.h Code designated as 'common' is compiled if TPM are used. Code designated as 'specific' is compiled only if the right specification has been selected. All files include tpm-common.h. Files in cmd/ include tpm-user-utils.h. Files in lib/ include tpm-utils.h. Depending on the specification, files may include either (not both) tpm-v1.h or tpm-v2.h.
