yes, NDA. plus it's USA-designed and supplied. i have deep abiding
concerns about sourcing any SoC that is by a USA-based company,
primarily because the parent company could be pressurised into *not*
supplying sufficient quantity, should the product itself become a huge
mass-volume success. yes, if you've not been reading slashdot, this
kind of political stupid tit-for-tat (China banning Cisco products,
U.S. banning Huawei products) really does happen.
the other concern is that we'd not even be able to get _small_
quantities (10k or so) without going through a USA-based supplier.
that requires insane credit references, credit checks, existence
checks, existentialist checks and so on.
whereas for e.g. that RTL8306 part, it's all over taobao in _huge_
quantities, and has been since 2007. the supply and use of that IC is
basically massively uncontrolled and uncontrollable.

on paper the spec was perfect, which is a pity.
