[hpsdr] HPSDR(Mercury, Pannylane, adn Metiz) and PowerSDR version

[Dave Larsen]

Tokio

The problem is that the  board set has a separate FPGA on each board.  The
Hermes has only one FPGA so the programming is simpler

You can use Programmer to program the metis board then use the metis board
as a jtag programmer to load the images into the mercury and Penelope or
Pennylane.

The manuals explain this process.
