Here you are a patch that adds big endian support for rv730 in r600
classic mesa driver. The BE modifications are almost the same as the DRM
/ DDX driver modifications
I used the mesa-demos to test the driver status on big endian platform.
Nearly all demos renders the same as on Intel architecture.
Nevertheless, there are still some issues in glReadPixels (r600_blit)
with some formats. I can't figure out exactly what and when data must be
swapped (set_tex_resoures, set_render_target...). Review of the patch
would be greatly appreciated.
It seems that r600g will be the default for Mesa 7.11 so I'll try to
enable big endian support for Gallium now.
