Nothing special. If you used SRCPV in PV where you are using an SCM in 
SRC_URI, that should be enough. The integer at the start of SRCREV will be 
incremented automatically if the revision changes, and if it doesn't but other 
values within the recipe change then PR will automatically be incremented 
above the initial value set in the recipe.

I believe as described in the page I linked above you should only need to set 
PRSERV_HOST.

Cheers,
Paul
