I had a lecture on the subject actually where EP93xx came up:
https://docs.google.com/presentation/d/1pv9MTCDpb0EgzrzicA9JF3pdUL6EcUmKhTavk5_hOHs

As seen it is considered a "fully developed product" and it would not
surprise me if Cirrus is taping out new EP93xx chips even.

This SoC is definitely on my shortlist of stuff we need to support.
(I wish Cirrus would provide some manpower but ...)
