Sergei,
How about cppi41 core? I could see only one post on that while searching davinci list. Did it get merged to any tree? 

Is there any updated patch on cppi4.1 core also?

Any comment on this?

Another option is to create arch/arm/ti-common to place all TI platform's common software, such as CPPI4.1 used both in DA8xx and AM3517.
