Sorry, I've missed that. The original reason was that qspi was missing
from linux's zynq-7000.dtsi, but we'll probably just need to update it
there, qspi is quite important for z-turn. I just see one potential
point of confusion in that spi0 overrides actual spi0 (spi0 at e0006000) in
zynq-7000.dtsi. While it is not used on Z-turn by default, it can
possibly be routed to one of the pins on an external connector. It can
still be addressed by the full name of course.
Thanks,
Anton
