[Skiboot] [PATCH v2 0/8] libstb: Advance TSS infrastructure

[Mauro S. M. Rodrigues]

The previous TSS infrastructure code in skiboot, although correct, was only
enough for some fundamental TCG software stack operations, like PCR extend and
eventlog, and other TSB work like secvar requires broader infrastructure.

In this series we introduced and switch to a complete TSS implementation,
supporting the previously existent operations, like PCR Extend, PCR Read and
EventLog for measurement, and including a new set of operations, until we're
able to remove the old implementation at patch 07.

Using an external implementation helps to diminish the maintenance burden at
skiboot side, brings code stability and makes easier to update TSS
infrastructure if necessary, for instance to get new features or to obtain new
fixes.

This implementation intruduces at patch 01 the ibmtpm20tss subtree from
https://git.code.sf.net/p/ibmtpm20tss/tss tag: v1.4.0.

Note that in order to reduce the ammount of code copied through the subtree we
select just the portion we need, the directory utils which represents tss 2.
