[hpsdr] USB Blaster Mode

[Bill Tracey]

At the risk of leaving someone out, there's a fair number of people 
responsible for the OzyBlaster code.

The original author of the FX2 code is  Kolja 
Waschk  (http://www.ixo.de/info/usb_jtag/).  The FPGA4fun guys got it 
working on their boards 
(http://www.fpga4fun.com/forum/viewtopic.php?t=483) so Phil Harman go 
interested in seeing if we could adapt it to the HPSDR 
boards.   Ramakrishnan Muthukrishnan  (VU3RDD) took on this work and 
with a little bit of help from me got it working on Ozy.   Phil H 
then searched far and wide for light weight programming tools so it 
could be done from a batch file.

Pretty neat - and all made possible by open source software.  If 
Kolja had done his original work closed source we'd not have been 
able to use his code and we all might be buying USB Blasters!

Cheers,
