Thanks for the patch. More than half the devices in this subtarget have a flash size < 16
MB (the current recommended minimum), so I agree with the approach here.

If somebody has strong opinions on this, and would for example rather see something like
ath79/tiny, feel free to speak up (and to send a patch ;-)

Otherwise I'll probably merge this patch early next week. Or sooner if some stakeholders
send their Acked-by.


Best,
Sander
