OK fine. I was going to enquire into the similarity of this embedded Intel
HW IP to the old StrongARM, Xscale, and PXA or whatever other
embedded Intel things that have been around for ages, sometimes IP
is inherited in the strangest ways. Oh well I guess we might see if we
look at the register maps a bit.
