Talked to hardware manufacturer and they applied the patch.
Still that SDMA is only used for NOR flash and only u-boot and its
environment are stored in nor flash. So not sure if that is going to
help in any case.
So I would really like few more suggestions OR confirmations about ARM
(cortex-A9 based imx6) (preemept)-RT support/patches are stable and
can be used for final products.
