Hi Richard, and everyone else:

Browsing the internet for "JFFS2 mtd" results in tutorials, articles
and github.gists0 that point to mtdblock.

In fact, even the MTD wiki mentions that JFFS2
needs mtdblock to mount a rootfs:

  http://www.linux-mtd.infradead.org/faq/jffs2.html

Moreover, I suspect there may be lots of users
that still believe mtdblock is somehow needed to
mount SquashFS.

I've taken a verbose route and added a pr_warn
warning if the devices are NAND. I don't think using
NAND without UBI is too wise, and given the amount
of outdated tutorials I believe some advertising
will help.

These patches are compile-tested only, as I don't
have devices ready to test, but I can undust some
boards and do some experiments if you think it's needed.

Oh, and PS: We also need to update the wiki.
