nora.c is misnamed. It's just a 'map' driver for memory chips which are 
mapped directly into the CPU's VM, which is what happens on a lot of ARM 
boards. It's not really CFI-specific at all, except that it happens to call 
the cfi_probe function and none other at the moment.

By changing a couple of defines for the address and size, you can make it
handle memory chips mapped anywhere in VM rather than just where my
particular board happens to have them.

Single Board Computer.

It just got less simple. We now make an attempt to do proper async handling 
of flash chips, and I'm just about to test it. If it works, I'll try to 
build up the courage to shift the erase stuff into a timer, and enable 
suspension of in-progress erases.
