kernel - TI sitara sdk

Following R. C. Nelson suggestion I updated to 4.1.10-ti-r21 kernel;
Does anyone know what is the TI AM335x SDK this kernel has been generated from?
I need to know to verify some underlying SDK issues are\are not fixed.

v02.00.00.00

http://git.ti.com/gitweb/?p=ti-linux-kernel/ti-linux-kernel.git;a=shortlog;h=refs/tags/ti2015.01

which would have been around "4.1.6-ti-r17"... or so..
