[PATCH 0/3] x86: Initial Trenchboot/SKINIT support

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

The Trenchboot project[0][1] project aims to develop and upstream support for
TCG DRTM support into various open source projects in the ecosystem, to
improve boot security.  Trenchboot has been discussed at previous
XenSummits[2], and the work across the ecosystem is extensively blogged
about[3].

This series forms the start of the work within Xen, and for now simply covers
the ability to boot in the AMD SKINIT/Secure Startup environment.

Full details are available in AMD APM Vol2 15.27 "Secure Startup with SKINIT"

Future work will cover related support for Intel TXT in a non-tboot system,
and the common logic to interact with the TPM and extend the hardware measured
chain of trust into dom0.
