The reason I moved away from xilinx-v2016.4 is that when I create boot.bin from
this version I get absolutely nothing on the UART console, and the PS_ERR_OUT
LED turns on: "PS error out is asserted for accidental loss of power, an error
in the PMU that holds the CSU in reset, or an exception in the PMU"

Not sure if the same, but it looks like I'm not the only one:

Assuming (???) the PMU FW might be related, since the u-boot-xlnx at that time
has no support for pmufw bundling in the boot.bin, it's kind of hard to test it
out.

At this point I'm going to wait for input from the masters of this... guys, I'm
willing to test, comment, improve, contribute. Please help me out here! ;)
