GA100 is a compute-only variant of GA102 that boots GSP-RM like a Turing.
Although architecturally like an Ampere, GA100 uses the same GSP-RM
firmware files as Turing, and therefore must boot it like Turing does.
In addition, as a compute-only part, GA100 has no display engine,
no VBIOS, and no graphics (GR) engine.
Since it doesn't have VBIOS, there is no FWSEC firmware, and so there is
no FRTS region that needs to be reserved or initialized.
Although Nouveau now supports GA100, there is currently no real support
for this GPU with either Clover or Rusticl/NVK, as both require a 3D
engine. This is in contrast with GH100, which does contain a GR engine
and is supported.
Also note that this patch partially reverts commit e8b3627bec ("nouveau:
don't attempt fwsec on sb on newer platforms."), which added fwsec
pointers to struct ga100_gsp erroneously.
