Hello Madalin,

Thank you very much for this summary that helps keeping an overview on the
current Freescale mainline DPAA effort (by the way, I am also very pleased to
see these patches getting to the mailing-lists, this is very important to us).

Now I would like to give all this a try on our P2041 board, the kmcoge4 for
which there is a DT in mainline. Could you please tell me on what kernel branch
these patches are based on ?

Best Regards

Valentin
