We discussed framebuffer endianess when introducing the driver,
in the thread linked near the FIXME comment in the code.

I proposed an untested fix but Noralf wanted to wait for testing,
which I find fair. I don't think anyone has tested on BE yet.

It's on my nice-to-have list, but not at the top, and has blockers,
so if anyone else can test on BE please do. I'd recommend testing
with an actual device to compare LE and BE behavior easily.


Kind regards
