I then made the following kernel configuration changes:
# CONFIG_OF_UNITTEST is not set
# CONFIG_OF_OVERLAY is not set
CONFIG_OF_UNITTEST has issues and might cause the failure, we are not
sure if it is because of our tree or upstream. This is the info I got
from our kernel maintainer, we will try to address the issue in 2018.1
release
Now my system boots again.
It seems to me there is some bug with either the DT overlay support in
the kernel, or with some portion of Xilinx's power management and/or
QSPI/SPI-NOR layer implementation which results in fatal errors in the
DT overlay support. I'll let Xilinx dig in further on that as I can now
move forward again.
Thanks for digging out the issues in QSPI and sending the patch in an
earlier email. We have verified your patch and applied it

Thanks,
