You might be right.  I expect that it is quite possible that we will
have an MI generic flash framework in the nearly immediate future, and
it is likely that my spiflash driver will be converted to it.  (Provided
that the framework, which has been created by Jared, is extended in
certain necessary ways -- namely it needs to support asynchronous
strategy() and it needs to grow support for RedBoot partitioning.)

If we have to revoke a major number to adapt to the common flash
framework, I'd rather revoke one that is only used for one small port
(Meraki Mini), rather than an MI one.

I'll know more in a week or so --once Jared is back from Ottawa and he
and I have discussed it further.
