/* For reasons unknown, people are in the habit of taking a 32-bit
* field with 2 possible values and packing it with, say, 2 bits. A
* non-robust encoding, using only 2 bits of a 32-bit field, is
* incredibly difficult to deal with when things go wrong, because
* there are a lot of things that get expressed as 0, 1, or 2. If
* you're scanning with jtag or dumping memory it is really hard to
* tell when you've hit the beginning of the struct. So, let's be a
* bit smart here. First, while it's common to let the enum count
* entries for you, when there are two of them, we can do the
* counting. And, let's set the values to something we can easily scan
* for in memory. Since '1' and '2' are rather common, we pick
* something that's actually of some value when things go wrong. This
* setup motivated by a use case: something's going wrong and having a
* manuf name of '1' or '2' is completely useless!
