The following series involves some code reorganization in the TPM code that I found useful in understanding the code.
Patches 3-5 simplify the hardware interface by only exporting three commands to the underlying TIS hardware (tpmhw_probe, tpmhw_transmit, tpmhw_set_timeouts).
Patches 8-10 simplify the parameters to the build_and_send_cmd() function.
The remaining patches are mostly just code reorg.
I have only compile tested these changes.
Kevin O'Connor (10): tpm: Add banner separating the TCG bios interface code from TCG menu code tpm: Avoid macro expansion of tpm request / response structs tpm: Simplify hardware probe and detection checks tpm: Add wrapper function tpm_set_timeouts() tpm: Move TPM hardware functions from tcgbios.c to hw/tpm_drivers.c tpm: Rework TPM interface shutdown support tpm: Simplify tcpa probe tpm: Introduce tpm_get_capability() helper function tpm: Eliminate response buffer parameter from build_and_send_cmd() tpm: Return returnCode from build_and_send_cmd() instead of via pointer param
