Review Comment:
I will try to dump a ROM code to see. I'm expecting that IAP may execute
multiple instructions and the flash re-programming requirement is that no code
should be executed from flash during reprogramming, so `up_irq_save` is here to
ensure there will be no interrupt during IAP execution.
Let me convert to draft while I'm figuring out all the details
