As I have previously stated, I think this is a mistake simply because
the firmware interface is a bad mapping on requirements for an FPGA,
especially once you account for the vast number of ways an FPGA can
get loaded and you take partial reconfiguration into account. I
happen to be at a face to face meeting with Greg today, so I'll pick
his brain a bit.
