I don't understand why if it can be validated, it can't be
autogenerated and validated by the same process. It seems like the
validation logic is going to be the same as autogeneration logic so
you might as well have it spit out the address and save having to
write them out by hand in each module, or in the root configuration
for bassaddresses.
