284ad706ad drm/nouveau: add support for GB20x
This commit adds support for the GB20x GPUs found on GeForce RTX 50xx
series boards.

Beyond a few miscellaneous register moves and HW class ID plumbing,
this reuses most of the code added to support GH100/GB10x.

32cb1cc358 drm/nouveau: add support for GB10x
This commit enables basic support for the GB100/GB102 Blackwell GPUs.

Beyond HW class ID plumbing there's very little change here vs GH100.

44f93b209e drm/nouveau: add support for GH100
This commit enables basic support for Hopper GPUs, and is intended
primarily as a base supporting Blackwell GPUs, which reuse most of
the code added here.

Advanced features such as Confidential Compute are not supported.

Beyond a few miscellaneous register moves and HW class ID plumbing,
the bulk of the changes implemented here are to support the GSP-RM
boot sequence used on Hopper/Blackwell GPUs, as well as a new page
table layout.

There should be no changes here that impact prior GPUs.

7c2d25f1e4 drm/nouveau/gsp: add common code for engines/engine objects
With minimal to no direct HW programming required, most nvkm_engine
implementations are nearly identical when running on top of GSP-RM.

Add a common implementation of the boilerplate, and use nvkm_rm_gpu to
expose the correct class IDs.

As they're now handled by common code, and there's no support for them
prior to GSP-RM support - this deletes the GA100 NVDEC/NVJPG/OFA HALs,
the GA102 NVENC/OFA HALs, and the AD102 GR/NVDEC/NVENC/NVJPG/OFA HALs.

0fac5141d6 drm/nouveau/gsp: add display class ids to gpu hal
Use display class IDs from nvkm_rm_gpu, instead of copying them from the
non-GSP HALs.

Removes the AD102 display HAL, which is no longer required as there's no
support for it without GSP-RM.

befe75ae0d drm/nouveau/gsp: add gpu hal stubs
With GSP-RM handling the majority of the HW programming, NVKM's usual
HALs are more elaborate than necessary, resulting in a fair amount of
duplicated boilerplate.

Adds 'nvkm_rm_gpu' which serves to provide GPU-specific constants and
functions in a more streamlined manner.

This is initially used in subsequent commits to store engine class IDs,
and replace the per-engine/engobj boilerplate with common code for all
GSP-RM supported engines - and is further extended when adding GH100,
GB10x and GB20x support.
