Thanks for your work on this,

I've tracked down all 54 MIO pins of the Parallella and cooked up the
equivalent DT patch. QSPI and USB still seem to be missing drivers
upstream; I reused the SPI driver for the QSPI with pinctrl and
Punnaiah's chipidea driver (not fully working) without pinctrl for lack
of group/function definitions. For testing purposes I've configured a
heartbeat trigger for the USER_LED (CR10).

To my disappointment these pinctrl additions did not fix one issue:
Whenever a write access to be handled by the bitstream (0x808f0f04) is
performed, the board hangs and the heartbeat stops. Would a bug in the
bitstream allow this to happen, or are more drivers missing to actually
make use of the PL in general? With a downstream ADI/Xilinx 3.12 kernel
that problem does not surface.

Regards,
Andreas
