Yes, I think this will have compatible issue if user don't have debug 
board for re-flash the NOR.

Will want to wake up from AUX in ASU, but I don't think ASU should have 
_NOR regression in as AUX wake up source_ issue.

We might could use hardware id we to difference the hardware ship with 
ASU, and make suspend resume behavior differently in ASU software/NOR. 
And this should not affect original GTA02 install ASU for update.
werner might need to help on this item and logic, including the initial 
set aux as wake up source and wake up source check for resume logic.

Yes, might be 3 weeks before in some ASU meeting.
