This worked great for me, and I got my amdcfi component to more or less work, 
but have one more hurdle to overcome:

The processor is an arm7t with a 32 bit bus. The flash is a 16 bit device. 
(The component can also be an 8 bit device, but I don't need this 
particularly.) In our actual hardware, we have a mapper that will read and 
register two 16 bit addresses on the flash and shift/concatenate them to form 
a single 32 bit word when the processor executes a 32 bit read. (This allows 
us to execute non-thumb instructions out of flash for example.) I haven't yet 
found a way to make the SID mapper do this. Is this currently possible? Am I 
looking in the wrong place? Am I going to have to do some re-writing?
