Subject: [PATCH 0/6] gpu: nova-core: Hopper/Blackwell prerequisites

I've based these Hopper/Blackwell prerequisites on top of Joel's and
Alex's changes, and also on top of my recent boot0/boot42 changes.

This makes it easier for both Timur Tabi to post his Turing support
(which he's about ready to do), and for me to post the actual
Hopper/Blackwell support, without generating conflicts.

Testing: This works as expected on Ampere and Blackwell (bare metal),
on my local test machine.

Here's a working branch, with my patches, if you would like to apply
locally:

John Hubbard (6):
  gpu: nova-core: print FB sizes, along with ranges
  gpu: nova-core: Hopper: basic GPU identification
  gpu: nova-core: Blackwell: basic GPU identification
  gpu: nova-core: factor .fwsignature* selection into a new
    get_gsp_sigs_section()
  gpu: nova-core: regs.rs: clean up chipset(), architecture()
  gpu: nova-core: use gpu::Architecture instead of long lists of GPUs
