Have there been (since the original posting) other instances of flash 
parts requiring quirks (like the original one introduced by Philippe De 
Muyter for the Numonyx chip)?
Is there any ongoing activity on this or any other reason to suggest it 
might be necessary to introduce such generic infrastructure (like the 
one in linux mtd, the way I understand it)?

If that's not the case, wouldn't Heicho's original patch in this thread
(http://patchwork.ozlabs.org/patch/86063/) just be good enough for the 
purpose?

Thanks,
Gerlando
