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.

v2: Check if bo object is NULL rather than checking size
     Move all vbios/firmware allocations into mman structure

Alex Deucher (17):
   drm/amdgpu: handle bo size 0 in amdgpu_bo_create_kernel_at (v2)
   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
   drm/amdgpu: move stolen memory from gmc to mman
   drm/amdgpu: move IP discovery data to mman
   drm/amdgpu: move vram usage by vbios to mman
