[LEDE-DEV] Fwd: porting arduino/linino boards into LEDE trunk

[Piotr Dymacz]

Hello Arturo,

Just my two cents, little bit off the topic.

Is there any specific reason to keep Arduino/Linino boards in "legacy
category" (ex. to have rootfs before kernel in image)?
Plus, why do all your boards have specified 64 KB nvram mtd partition?
AFAIK, nvram is not used on QC/A based devices.

Cheers,
Piotr
