Zynq UltraScale+ MPSoC: 2016.3 PMU firmware can hang when the debug prints are enabled.


When Common Clock Framework (CCF) and Power management (PM) are enabled, Linux does not boot.

The PMU firmware will hang when the debug prints are enabled. This is because Linux is trying to turn off the UART which is being used by the PMU firmware.


To work around this issue, do not use UART prints in the PMU firmware, or else use the UART that is being used by Linux.
