* The kernel driver is only responsible for loading the HuC firmware and
* triggering its security authentication. This is done differently depending
* on the platform:
+ *
* - older platforms (from Gen9 to most Gen12s): the load is performed via DMA
* and the authentication via GuC
* - DG2: load and authentication are both performed via GSC.
* not-DG2 older platforms), while the authentication is done in 2-steps,
* a first auth for clear-media workloads via GuC and a second one for all
* workloads via GSC.

* On platforms where the GuC does the authentication, to correctly do so the
* HuC binary must be loaded before the GuC one.
* Loading the HuC is optional; however, not using the HuC might negatively
