The latter. It loads the SPL code, and then bails out with "invalid boot mode" 
because it cannot read the QSPI from within the SPL.

topic-miami

It's not in your list, but the QSPI is connected in the same way as the Zed.

Ah, wait... You're talking about u-boot from denx.de. I didn't know that the 
Xilinx code had already merged into that. I was looking at the u-boot-xlnx 
repository.

In that case, no I haven't tried current master yet. Will do.

I might want to put some effort into mainlining our u-boot code for the board 
then.
