Version 2 summary,
addressed the following review comments:
- break up patch into 3 separate commits;
- add more details in the commit logs;
- I added links to the TCG TPM standard documents as this device
model communicates to the TPM device (hw / swtpm) via
tpm_tis_commom.c which is standard compliant;
- the TPM SPI model implementation in itself is not platform
specific. However, the SPI interface is via the PowerNV SPI
bus master, thus it is only supported on the PowerNV platform
- change all qemu_log() calls to trace events;
- move static global variables to the TPMStateSPI struct;
- fixed code formatting (verified by scripts/checkpatch.pl);
- per requests, make the code more readable by using self-
explanatory #defines and adding comments;
- added some documentation support (tpm.rst);
- beefed up the unit test exercising major supported locality
functionality
Tests: 'make check' and 'make check-avocado'
