To make it more clear - we intend to keep all VRT/UHD related FPGA
code in place and just replace/change interaction with RF part. May be
we'll have to slightly extend VRT/UHD code for our specific purposes,
but it will be minor changes.

In other words - all our changes will be to support a new platform
seamlessly with existing UHD code.
