That output looks good and consistent now. I suppose the lock-up is
related to the long delay that the printing implies. You may filter out
some uninteresting reports by adding "if (phys != 0x7c017000)" as
condition (that address is - in your build - the zero page where the
hypervisor regions gets mapped to for the root cell).

Maybe there is some subtle issue related to the cores. You have a board
with 2 A35 and 1 A72 cores, right? How about confining the startup tests
on one of each core types for now? You could bring the cores of the
other type offline (echo 0 > /sys/devices/system/cpu/cpuX/online),
adjust the config to only contain the online cores, and retry.
