[Intel-xe] [PATCH 00/12] GSC FW loading

[Daniele Ceraolo Spurio]

the GSC (Graphics Security Controller) is the root of trust for content
protection operations (PXP, HDCP), so loading the the GSC FW is a
prerequisite for those features. Loading the FW is required to turn off
the GSC forcewake well (which we must turn on to enable GSCCS idleness)
and therefore allows MC6 entry.

The GSC FW uses 3 separate versions: release, compatibility and
security. The compatibility version is the one that dictates whether the
driver knows how to interface with the binary so that's the one we match
against, but we also fetch the other two for debug information.

The GSCCS is used to both load the FW (via the GSC_FW_LOAD command) and
to send heci packets to it (via the GSC_HECI_PKT command).

Note: the flr patch from Andrzej is being reviewed separately, I've just
included it here because it is a dependency.
