Gather all the TPM2 definitions and structures in the internal header
file drivers/char/tpm/tpm.h into the command header, including:
- Command codes, return codes and definitions from the public and
internal tpm.h files.
- Structures defined in numerous TPM driver C modules.
The definitions moved to these files correspond to the TCG specification
for TPM 2 family:
TPM 2.0 Library
