[hpsdr] EEPROM Programming

[Philip M. Lanese]

Phil

If you purchase all the chips from one distributor he will program them for you
for very little extra (negotiating point).  Then you have a pre-tested device
when it arrives.  Most (if not all) distributors provide the service for any
device that is programmable i.e. FPGA, EEROM, CPU with embedded ROM, etc.
