drm/ast: Swap framebuffer writes on big-endian machines
Swap the pixel data when writing to framebuffer memory on big-endian
machines. Fixes incorrect output. Aspeed graphics does not appear to
support big-endian framebuffers after AST2400, although the feature
has been documented.
There's a lengthy discussion at [1].
v5:
- avoid restricted cast from __be16 (kernel test robot)
