drm: atari: Add a DRM driver for Atari graphics hardware
Supported formats:
- C[1248],
- RG16 (both standard DRM (little-endian) and native (big-endian)),
- XR24.
RG16 and XR24 are only supported with the underlying RGB565 hardware
mode on Falcon, and are subject to hardware restrictions (limited to
e.g. "qvga" and "hvga" modes).
All formats use a shadow buffer (TODO: BE RG16 buffers from ST-RAM).
Initial mode setting works, later mode changes sometimes fail.
Developed and tested on ARAnyM.
Probably this should not be under /tiny ;-)
