I followed the Arrow SoCKit recipies on rocketboards.org. I still don't know what went wrong, but without any apparent change in the procedure I'm now able to boot from QSPI.

Regarding debugging of the BootROM I simply used DS-5 and the USB blaster JTAG interface in the SoCKit dev board. To connect to the target during "cold start" I did the following:

1) press and hold down both the HPS_RST and the WARM_RST buttons. ( they are connected to HPS_NPOR and HPS_RST respectively)

2) release only the HPS_RST button

3) connect to the target via the DS-5 debugger. Use a "debug configuration" that only connects to the target.

4) issue the debugger command "interrupt"

5) release the WARM_RST button

This catches the target at address 0x0, and from there you can single step through the BootROM.
