Hello folks,

 I'm doing the board "bring up" with Linux on top of Freescale Hypervisora on customized T1042 board. And, Linux Kernel versionis 4.12.

 I'm having a hard time trying to figure why during boot up, the Bman and Qman are intialized as shared and slave mode.  I am expecting all the cores having its on Bman and Qman created, not this shared and slave.  Can anybody please tell me how to configure the Kernel or DTS to make this shared and slave mode disabled ?
