[PATCH v3 0/5] TPM TIS SPI Support

[dan tan <dantan@linux.vnet.ibm.com>]

*** BLURB HERE ***

Support TPM for SPI (Serial Peripheral Interface)

Revision 3 summary:
  device support:
    - moved variable tis_addr from TPMStateSPI struct to local
    - added the VM suspend/resume support:
      - added vmstate_tpm_tis_spi declaration
      - added tpm_tis_spi_pre_save() function
    - fixed trace formatting string

  qtest:
    - removed the function prototypes declaration
    - fixed code format to comply with convention
    - changed function names and variable names to be the same
      as the tpm-tis-i2c test.
    - change hard coded numbers to #define's with meaningful
      names that are identifiable with spec documentation

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
