[PATCH 00/14] rework stolen pre-OS fb allocation handling

[Alex Deucher]

Split the allocations into two so we can still support the S3
workarounds required on some platforms while also avoiding
any artifacts when transitioning from bios to driver.

In the future we could integrate handling of the ip discovery
data and other vbios allocations into this helper function
to consolidate handling of all of the vbios reservations.

Alex Deucher (14):
  drm/amdgpu: handle bo size 0 in amdgpu_bo_create_kernel_at
  drm/amdgpu: use create_at for the stolen pre-OS buffer
  drm/amdgpu: use a define for the memory size of the vga emulator
  drm/amdgpu: move stolen vga bo from amdgpu to amdgpu.gmc
  drm/amdgpu: move keep stolen memory check into gmc core
  drm/amdgpu: add support for extended stolen vga memory
  drm/amdgpu/gmc: add new helper to get the FB size used by pre-OS
    console
  drm/amdgpu/gmc6: switch to using amdgpu_gmc_get_vbios_allocations
  drm/amdgpu/gmc7: switch to using amdgpu_gmc_get_vbios_allocations
  drm/amdgpu/gmc8: switch to using amdgpu_gmc_get_vbios_allocations
  drm/amdgpu/gmc9: switch to using amdgpu_gmc_get_vbios_allocations
  drm/amdgpu/gmc10: switch to using amdgpu_gmc_get_vbios_allocations
  drm/amdgpu: drop the CPU pointers for the stolen vga bos
  drm/amdgpu/gmc: disable keep_stolen_vga_memory on arcturus
