Yes, that one was abandoned because I was not able to get it up and running.

Yes, I remember that there is something wrong with the "reset framework".

TI isn't doing a really good job in making things compatible to mainline
Linux (which is to some extent understandable - but makes it very complex
if you don't want to use a TI kernel).

Generally my hope is that the 5.0 SDK can be made working on the 3.12
(or 3.15) kernel.
