Boot Survivability is a software based workflow for recovering a system
in a failed boot state. Here system recoverability is concerned with
recovering the firmware responsible for boot.

This is implemented by loading the driver with bare minimum (no drm card)
to allow the firmware to be flashed through mei-gsc and collect telemetry.
The driver's probe flow is modified such that it enters survivability mode
when pcode initialization is incomplete and boot status denotes a failure.

A survivability_mode sysfs entry is an indication of this mode.

Rev2: Initialize mei-gsc and vsec
      abstract survivability mode
      remove extra sysfs entry

Riana Tauro (3):
  drm/xe: Add functions and sysfs for boot survivability
  drm/xe: Enable Boot Survivability mode
  drm/xe: Initialize mei and vsec in survivability mode
