But you could still start up quickly from flash without having to memcpy 
the entire kernel into RAM first, then once you're running copy the kernel 
text into RAM and alter the page tables so you're running from the RAM copy 
instead of the flash.

This gives you the fast startup of XIP without the runtime pain of XIP. But 
it's probably overkill.
