Adding a 'requires' statement is what I did my platform's
flash driver. However, Atmel's description of the problem is a
bit vague; not everybody may actually encounter it. And AFAIK
Atmel is planning to replace the flash chip with another one,
so the problem will probably go away some time.
In the light of this, it is probably better to still allow these
platforms to be built without the workaround.
