It might make sense to have this run-time configurable/switchable via
L1CTL or some other means.

It would be much appreciated if you could bring it into a state where it
can cleanly coexist with the other existing code, at which point it
would become mergeable.  I can see two options:

1) make the functionality available but not enabled by default, so a
   L1CTL command can configure + enable your code at the user option

2) really introduce a new firmware build target.  It's possible, but we
   already have too many firmware images we build for each hardware
   target, and I'd prefer to see that number shrinking rather than
