I wish the series had a real cover letter which explains the big picture
in more detail.

What I didn't really get so far, is it really necessary to support multiple
chip selects within a single mtd?
You changes introduce hard to maintain changes into the spi-nor/mtd core code
which alert me.
Why can't we have one mtd for each cs and, if needed, combine them later?
We have drivers such as mtdconcat for reasons.

Thanks,
