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.
