Hi Andreas,

I have regenerated this series, but have not actioned this just yet. I
think adding a config switch is probably not the right solution, as
its just a device model. If every device model has a config switch
then isnt creating everyone config process going to be excessively
tedious? perhaps it can just live next to obj-y=ssi.o? I.E. if you
have SSI, then you have m25p80. I cant think of a case where you would
want SSI but need to exclude m25p80 from the build.

Regards,
Peter
