I prefer to sort it by the wafer ID (the number after w in the official 
ID).

The current document can be explained to follow the alphabetical order
or the wafer ID.

P.S. there's some error in the V3s datasheet position, and if it's fixed
we can still continue to make the two kinds of order both meaningful ;-)

You should know who your audience is. Whoever is going to end up here
to have a list of the SoC names and their datasheet is very likely to
not know by heart the wafer IDs, while anyone that can read knows the
alphabet.
