This patch set adds Zero FrameBuffer (ZFB) support to amdgpu.  This
feature is used for emulators and early silicon before vram is
available.  System ram is used for "vram".

Feifei Xu (6):
  drm/amdgpu: add new member in amdgpu_mc for zfb support
  drm/amdgpu: add amdgpu module parameter for zfb
  drm/amdgpu: init zfb start address and size
  drm/amdgpu: user reserved zfb to init vram base offset and size
  drm/amdgpu: enable physical transaction for ptd/pde when ZFB is
  drm/amdgpu: program system bit for pte/pde when ZFB is enabled

Hawking Zhang (1):
  drm/amdgpu: program AGP aperture as frame buffer when ZFB is enabled
