if you are booting with serial console, you could try to use earlycon
boot parameter to get more output. Though, I do not have the
parameters for that system at hand. You could try 'earlycon' without
parameters or perhaps 'earlycon=pl011,0x87e024000000' or similar (not
sure if that works, maybe check devicetree).
