[Intel-xe] [PATCH v7 0/4] drm/xe: Rework multi tile device memory initialization

[Michael J. Ruhl]

The vram initialization path does not take into account
each tile's actual memory size.

While updating this, simplify the rebar algorithm and clarify
some helper functions.

v2: Address review comments
    - separate tile sizing to the initial patch
v3: Re-add deleted warning for small bar systems
v4: Address review comments
    - stolen size check should be against pci resource
    - limit size (patch 2) to keep bisection correct
v5: Include actual memory size for Xe level for use (1:1 map for xe_migrate,
    for example)
v6: Limit gt memory size to visible size (small bar)
    Fix forced resize missed __fls
v7: Use GPU offset information (helper) for PT rather than IO offset

Michael J. Ruhl (4):
  drm/xe: Rework size helper to be a little more correct
  drm/xe: Simplify rebar sizing
  drm/xe: Size GT device memory correctly
  drm/xe: Rename GPU offset helper to reflect true usage
