I am not convinced about this. fpga entry in config defines link to
bitstream partition and likely it will work for default config but
you can describe multiple configurations and have multiple bistreams
in partitions and by this you will
lose capability to extract/load different or multiple bitstreams.

Look at doc/usage/fit/multi-with-fpga.rst and describe multiple
different config nodes with different bitstream and try to
load them with your patch applied.

Thanks,
Michal
