Subject: [PATCH] drm/amdgpu/gfx10: new approach to load gfx10 me fw (v4)
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
gfx10 allows to only upload me jumptable while save the whole
me image at gtt memory.
v2: program CP_ME_IC_BASE_CNTL to default value
v3: switch to use amdgpu_bo_create_reserved to create me fw bo
v4: split common code from gfx10 code
