It has been tested on ARAnyM using a work-in-progress Atari DRM driver. Changes compared to v1: - Consider arm, aarch64, microblaze, s390, and sh in endianness checks, - Add Acked-by, - Add swap32() intermediate helper, - Fix 16 bpp formats on big-endian, - Add support for big-endian XRGB1555 and RGB565, - Fix printing of big-endian fourcc values, - Fix pwetty on big-endian. Please refer to [2] for related Linux DRM patches and background information. Thanks for your comments!
