Are you talking about storing the optimized autocalibration values in FLASH, 
as discussed on IRC some time ago? I don't know if somebody is working on 
this. I only know that AMCC is working on a fix for the autocalibration on 
Kilauea. Not sure if this effects the bootup time, I can only hope it does.

Again, if you decide that that's the way to go, then I will not object.
