That's what I was afraid of.  Sigh.

I think some binary partition table format that can be
used by _all_ MTD consumers should be defined.  How
that table should be communicated to the kernel in the
device tree case we can discuss later, then.  Maybe
something as simple as storing it in flash, and have a
"partition-table-offset" property or something like that.

This is something the MTD people will have to buy into
of course.
