It can. We have enabled the interrupts through ACPI on Xilinx I2C block and it works great.
For the SPI block we currently have an issue with our FPGA. Luckily the driver works just fine in the polling mode. By just making the interrupts optional makes the same driver usable on a wider range of hardware platforms, with or without the interrupts.

Thanks,
