It's not really all that much more configurable than the A-profile
cores; I've just been a bit more careful to actually make our
emulation reflect what the hardware actually does... a really
careful testing of the A profile cores would want to test
the various different cortex-* CPUs individually to make
sure they UNDEFfed on the features they didn't have, and so on.
