Hi, Thanks for the patch, I'll try it out tomorrow to make sure it
doesn't break my board, and I hope Rudolf can do the same. In the
future, please use unified diffs (diff -u or just svn diff), much easier
to read. Your patch also needs a Signed-off-by: line before we can commit.

any reason not to just do enable_flash_vt823x here, instead of copying
the code?

Do you have the vt8235 datasheet? I think this works on it as well.
