DRM Rust changes for v7.2-rc1

- Driver Core (shared via signed tag dd-lifetimes-7.2-rc1):

  - Introduce Higher-Ranked Lifetime Types (HRT) for Rust device
    drivers, allowing driver structs to hold device resources like
    pci::Bar and IoMem directly with a lifetime tied to the binding
    scope, removing the need for Devres indirection and ARef&lt;Device&gt;.

  - Replace drvdata() with scoped registration data on the auxiliary
    bus, using the new ForLt trait to thread lifetimes through
    registrations. Remove drvdata() and driver_type.

- DRM:

  - Add GPUVM immediate mode abstraction for Rust GPU drivers:
    - In immediate mode, GPU virtual address space state is updated
      during job execution (in the DMA fence signalling critical path),
      keeping the GPUVM and the GPU's address space always in sync.

    - Provide GpuVm, GpuVa, and GpuVmBo types for managing address
      spaces, virtual mappings, and GEM object backing respectively.

    - Provide split-merge map/unmap operations that handle partial
      overlaps with existing mappings.

    - drm_exec integration for dma_resv locking and GEM object
      validation based on the external/evicted object lists are not
      yet covered and planned as follow-up work.

  - Introduce DeviceContext type state for drm::Device, allowing
    drivers to restrict operations to contexts where the device is
    guaranteed to be registered (or not yet registered) with userspace.

  - Add FEAT_RENDER flag to the Driver trait for render node support.

- Nova:

  - Hopper/Blackwell enablement:
    - Add GPU identification and architecture-based HAL selection for
      Hopper (GH100) and Blackwell (GB100, GB202).

    - Implement the FSP (Foundation Security Processor) boot path used by
      Hopper and Blackwell, including FSP falcon engine support, EMEM
      operations, MCTP/NVDM message infrastructure, and FSP Chain of
      Trust boot with GSP lockdown release.

    - Add support for 32-bit firmware images and auto-detection of
      firmware image format.

    - Add architecture-specific framebuffer, sysmem flush, PCI config
      mirror, DMA mask, and WPR/non-WPR heap sizing.

  - GSP boot and unload:
    - Refactor the GSP boot process into a chipset-specific HAL,
      keeping the SEC2 and FSP boot paths separated cleanly.

    - Implement proper driver unload: send UNLOADING_GUEST_DRIVER
      command, run Booter Unloader and FWSEC-SB upon unbinding, and run
      the unload bundle on Gsp::boot() failure. This removes the need
      for a manual GPU reset between driver unbind and re-probe.

  - GA100 support:
    - Add support for the GA100 GPU, including IFR header detection and
      skipping, correct fwsignature selection, conditional FRTS boot,
      and documentation of the IFR header layout.

  - VBIOS hardening and refactoring:
    - Harden VBIOS parsing with checked arithmetic, bounds-checked
      accesses, and FromBytes-based structure reads throughout the FWSEC
      and Falcon data paths. Simplify the overall VBIOS module
      structure.

  - HRT adoption:
    - Use lifetime-parameterized pci::Bar directly, replacing the
      Arc&lt;Devres&lt;Bar0&gt;&gt; indirection. Replace ARef&lt;Device&gt; with &amp;'bound
      Device in SysmemFlush and the GSP sequencer. Separate the driver
      type from driver data.

  - Misc:
    - Rename module names to kebab-case (nova-drm, nova-core).

    - Require little-endian in Kconfig, making the existing assumption
      explicit.

- Tyr:

  - Define comprehensive typed register blocks for GPU_CONTROL,
    JOB_CONTROL, MMU_CONTROL (including per-address-space registers),
    and DOORBELL_BLOCK using the kernel register!() macro. This replaces
    manual bit manipulation with typed register and field accessors.

  - Add shmem-backed GEM objects and set DMA mask based on GPU physical
    address width.

  - Adopt HRT: separate driver type from driver data, and use IoMem
    directly instead of Devres for register access during probe.

  - Move clock cleanup into a Drop implementation.

DRM Rust changes for v7.2-rc1

- Driver Core (shared via signed tag dd-lifetimes-7.2-rc1):

  - Introduce Higher-Ranked Lifetime Types (HRT) for Rust device
    drivers, allowing driver structs to hold device resources like
    pci::Bar and IoMem directly with a lifetime tied to the binding
    scope, removing the need for Devres indirection and ARef&lt;Device&gt;.

  - Replace drvdata() with scoped registration data on the auxiliary
    bus, using the new ForLt trait to thread lifetimes through
    registrations. Remove drvdata() and driver_type.

- DRM:

  - Add GPUVM immediate mode abstraction for Rust GPU drivers:
    - In immediate mode, GPU virtual address space state is updated
      during job execution (in the DMA fence signalling critical path),
      keeping the GPUVM and the GPU's address space always in sync.

    - Provide GpuVm, GpuVa, and GpuVmBo types for managing address
      spaces, virtual mappings, and GEM object backing respectively.

    - Provide split-merge map/unmap operations that handle partial
      overlaps with existing mappings.

    - drm_exec integration for dma_resv locking and GEM object
      validation based on the external/evicted object lists are not
      yet covered and planned as follow-up work.

  - Introduce DeviceContext type state for drm::Device, allowing
    drivers to restrict operations to contexts where the device is
    guaranteed to be registered (or not yet registered) with userspace.

  - Add FEAT_RENDER flag to the Driver trait for render node support.

- Nova:

  - Hopper/Blackwell enablement:
    - Add GPU identification and architecture-based HAL selection for
      Hopper (GH100) and Blackwell (GB100, GB202).

    - Implement the FSP (Foundation Security Processor) boot path used by
      Hopper and Blackwell, including FSP falcon engine support, EMEM
      operations, MCTP/NVDM message infrastructure, and FSP Chain of
      Trust boot with GSP lockdown release.

    - Add support for 32-bit firmware images and auto-detection of
      firmware image format.

    - Add architecture-specific framebuffer, sysmem flush, PCI config
      mirror, DMA mask, and WPR/non-WPR heap sizing.

  - GSP boot and unload:
    - Refactor the GSP boot process into a chipset-specific HAL,
      keeping the SEC2 and FSP boot paths separated cleanly.

    - Implement proper driver unload: send UNLOADING_GUEST_DRIVER
      command, run Booter Unloader and FWSEC-SB upon unbinding, and run
      the unload bundle on Gsp::boot() failure. This removes the need
      for a manual GPU reset between driver unbind and re-probe.

  - GA100 support:
    - Add support for the GA100 GPU, including IFR header detection and
      skipping, correct fwsignature selection, conditional FRTS boot,
      and documentation of the IFR header layout.

  - VBIOS hardening and refactoring:
    - Harden VBIOS parsing with checked arithmetic, bounds-checked
      accesses, and FromBytes-based structure reads throughout the FWSEC
      and Falcon data paths. Simplify the overall VBIOS module
      structure.

  - HRT adoption:
    - Use lifetime-parameterized pci::Bar directly, replacing the
      Arc&lt;Devres&lt;Bar0&gt;&gt; indirection. Replace ARef&lt;Device&gt; with &amp;'bound
      Device in SysmemFlush and the GSP sequencer. Separate the driver
      type from driver data.

  - Misc:
    - Rename module names to kebab-case (nova-drm, nova-core).

    - Require little-endian in Kconfig, making the existing assumption
      explicit.

- Tyr:

  - Define comprehensive typed register blocks for GPU_CONTROL,
    JOB_CONTROL, MMU_CONTROL (including per-address-space registers),
    and DOORBELL_BLOCK using the kernel register!() macro. This replaces
    manual bit manipulation with typed register and field accessors.

  - Add shmem-backed GEM objects and set DMA mask based on GPU physical
    address width.

  - Adopt HRT: separate driver type from driver data, and use IoMem
    directly instead of Devres for register access during probe.

  - Move clock cleanup into a Drop implementation.

Some of the GPU documentation pages are quite long, with various levels
of details. Add document internal tables of contents to the larger
documents to make them easier to navigate.

The index.rst in the sub-directories have toctrees, which provide
similar overviews.

Fix one missing newline at the end of drm-uapi.rst while at it,
primarily because rst should have it, and secondarily because my editor
rst mode refuses to save the file without it.
