Don't bet on it.  That's not how it works (unfortunately.)

Just look at the many serial port inventions dreamt up by SoC designers -
everyone is different from each other.  Now consider: why didn't they use
a well established standard 16550A or later design?

Also consider why ARM Ltd designed the PL010 and PL011 primecells which
are different from the 16550A.

This &quot;need to be different&quot; is so heavily embedded in the mindset of the
hardware people that I doubt &quot;providing consolidated implementations&quot;
will make the blind bit of difference.  I doubt that hardware people
coming up with these abominations even care one bit about what's in
the kernel.
