| Subject: drm/msm: Fix GMEM_BASE for gen8 |
| |
| From: Rob Clark <robin.clark@oss.qualcomm.com> |
| |
| [ Upstream commit dc220915ddb2d1c646a7d0816b398e73ed5a5d50 ] |
| |
| This should also be zero for gen8. This does change a7xx-gen1 to zero. |
| It was almost certainly incorrect before, but we have no such devices in |
| CI currently. |
