I haven't reviewed in details yet, just a minor comment about naming...

Technically it's also "SBE" on P8 :-) I'm not sure what the name of the
little engine they use for both SBE and SLW there, so I put everything
under "SLW".

On P9 it's Peppy's doing both the "STOP image" (ex-SLW) and SBE job.

So I think we should probably just have sbe_p8.c and sbe_p9.c both
exporting their respective function and move the p8 one out of slw.c
