braswell is essentially cherrytrail which is very nearly identical to 
baytrail except for an oscillator frequency. I tested SOF on Cyan a 
number of times in the past, so all the plumbing should already be there.
The only caveat is that there is quite a bit of DMA rework at the moment 
so there might be some re-testing required if you take the latest 
development branch.
Also our module load/reload tests failed, but it's more of a dependency 
with the max98080/TI aux chip that's not well handled than SOF proper.
