That still doesn't explain why removing one of the two accelerometers is
a good idea.  What is the benefit?  Why not remove them both?
Is it that all the programs that use the accelerometers (as of now) only
use one of the two?  Is it that having two accelerometers introduces
layout difficulties?  Is it that there aren't enough interrupt lines on
the SoC to properly support the two accelerometers? ...

Since it was decided to remove it, there must have been some kind of
expected benefit.

I actually have the same question for the audio-amp: why remove it?
But that one is a bit more complicated, because I'm not sure what is
this "audio-amp" anyway (is it the thing that drives the
headphone plug?)
