How does CM handle that code needs to be linked? You can’t just copy the bin blob stuff around. Else every user will have to build his own CM image. That’s doesn’t make sense to me.
I was always hoping that one could “update” the Android parts “around” the SoC vendor/ODM parts. But at least from my experiences with the FP2 code, this is not possible (see the modified .so in my link).
