Still makes no difference. If Nokia factories could only handle one variety of display controller / power regulator / USB controller / etc, they would've been out of business long ago.
This is a company who had probably the single most diverse product portfolio in the entire industry, stretching to at least hundreds of products. Throw in the prototypes and you're up to thousands. And this is going from the very very cheapest 1110, right up to the N9 and other smartphones.
What you're saying makes absolutely no sense, sorry.
