Hi Jens,

A few small nitpicks below:

regarding the sort order, I'd say that at91sam9g20ek is not between at91sam9g15ek and at91sam9g25ek (both part of the at91sam9x5 familiy). I would place it before at91sam9g45m10ek. That comment is also valid for the family_, mach_ and dtb_ definitions

These can probably be updated to 4.1

Everything else seems OK, thanks for your patch.

I think you should explain why. It's because you're not interested in alphabetic ordering here, but rather "release date" ordering of the platform. Is that correct ?

Indeed.

Jens, can you fix those two issues and send an updated version of your patch ?

Thanks!

I'd say that I'm more interested in grouping by families and that indeed would be almost the same as the release date order.
The sam9g20 is almost the same as a sam9260 but is quite far from the sam9x5 family.
