I assume you mean static configuration a config with OF_CONTROL disabled.
Ok, i have tried to boot that with bootgen. That does not work.
Loading that into memory and booting it from within the debugger works
though. In both cases with or without OF_CONTROL enabled.

So my main focus is to test CONFIG_ARMV7_NONSEC to boot linux in 
normal mode. I wanted to test recent mainline with that. So focusing on 
u-boot SPL is to far off my targets. So i am happy with hardware debugger 
loadeing for the time beeing.

Getting back to CONFIG_ARMV7_NONSEC. This is unfortunatly not working with the 
Zynq.  Currently the board switches to monitor mode but when the u-boot 
switches to normal mode it jumps to PC:0xc  (LR:0x10) which seems like a data 
abort exeption or some other secure mode violation exception?
Is there a good way to find out what happened? I am currently stuck with this 
and my local FAE has also no idea. Attached is a patch which at least works 
until the return from the monitor mode.

Best regards
