[PATCH 00/16] Add vTPM support to SLOF

[Stefan Berger]

The following series of patches adds TPM support to SLOF.
In particular it adds the following:

- TPM drivers for hardware interface and CRQ interface
- TPM initialization
- TPM logging area and firmware API to transfer it to the OS
  (measurements are visible in sysfs)
- Some measurement code (Static Core Root Of Trust)
- TPM menu (accessible via 't' key during boot if TPM is available)
- Firmware API extensions following Power Firmware Doc
  (to make trusted grub work)

Necessarily, some of its parts are written in Forth, many are written
in 'C'. The extensions are known to work with QEMU for ppc64 running Linux.

Patches 4-6 will eventually need to be merged to avoid compiler warnings
related to unused functions.

Regards,
    Stefan
