Are you aware of any other MSP430 peripherals which steal memory blocks like 
the USB interface? If this is something that we'll see more of as TI creates 
more MSP430 variants, then it may be necessary to devise a clean, generalized 
way to deal with varying memory maps within a given part. Maybe just defining 
different part ID variants (e.g. -mmsp430f5529usb, -mmsp430f5529nousb, etc.) 
would be good enough, or maybe that would become too cumbersome if there's ever 
a part with a lot of memory map variability.
