Sorry for the late review, but it makes littel sense to add individual README.* files for each and every CONFIG option. Please add the documentation (with a little less verbocity) to the top level README instead.
Minkyu: can you provide an quick-updated patch with the doc in the top level README? I'll rebase and replace accordingly.
Best regards,
Wolfgang Denk
Amicalement,
