[PATCH v4 0/6] gpu: nova-core: add GA100 support

GA100 is an odd GPU. Architecturally, it's an Ampere. However, it
uses the same GSP-RM boot process as a Turing. Its VBIOS, for whatever
reason, has an IFR header that precedes the PCI ROM header and must
be skipped. In addition, the FRTS window size must be set to 0 just
because it's a GA100.

So add all the missing code that GA100 needs to be supported. There was
some infrastructure already for GA100 (e.g. the FbHal), but it was
incomplete.

Changes in v4:
1) Added a couple missing reviewed-bys
2) Removed IFR header v1/v2 "expect" comment

Timur Tabi (6):
gpu: nova-core: use correct fwsignature for GA100
gpu: nova-core: do not consider 0xBB77 as a valid PCI ROM header
signature
gpu: nova-core: only boot FRTS if its region is allocated
gpu: nova-core: add FbHal::frts_size() for GA100 support
gpu: nova-core: skip the IFR header if present
gpu: nova-core: enable GA100
