In order to keep user-space compatibility, we want in certain

This affects, not only, Amlogic, Allwinner or Rockchip devices

with ARM Mali GPUs using an userspace Blob.

This option is not supported by upstream developers and should be

removed as soon as possible and be considered as a broken and

legacy behaviour from a modern fbdev device driver.

those drivers are still available, but their use is highly
