I suspect people are getting pretty tired of me posting "I can't reproduce
that" comments. But, I can't reproduce that. I grabbed build 608, build
a new kernel from the olpc-2.6 git head, and it worked just fine. So I
patched in the current version of the driver, and it worked just fine.
I cannot reproduce the image quality problem either way, of course.
Do note that you need to bring in the new ov7670.c along with cafe_ccic.c.
They're a set.
I'll send Andres a patch so that we're at least all working with the same
version of the driver. Then we can keep trying to figure out just what is
going on here.
