Unfortunately, the approach of peeling open the HDF file and consuming
its content is problematic.  The HDF file contents are fundamentally in
a tool dependent format, and these contents are meant to be accessed
indirectly through HSI interfaces.

Moving forward, we would like to implement a meta-xilinx-tools layer
with dependencies on Xilinx maintained tools (e.g. HSI) instead of
breaking open the HDF in this fashion.

Thanks
