I'm not a big fan of "legacy" as a description because it conveys very
little information.  You're adding support for a "non-legacy" SoC, so
now there are "legacy" ones and "non-legacy" ones.  Next year there
will be another new SoC, and then there will be *two* kinds of
"legacy" ones that must be distinguished plus the next "non-legacy"
one.

You mentioned "Pro5" as an example of "legacy," which is a good start.
Are there any others?  If Pro5 is the only one, you could just use
"pro5" where you now use "legacy."
