[hpsdr] Can hpsdr fpga firmware be temporarily updated by an application in realtime?

[John Marvin]

There has never been a release version of firmware for Hermes that 
supported 7 receivers. There have been at least one "prototype" version 
that supported 7, but that version will hang every once in a while. I 
believe the bug was related to being to close to the "edge" of being 
full, so I don't think 7 receivers will ever be possible in Hermes 
without a) throwing every other feature out, and 2) finding ways (if 
possible) of trimming the remaining code. It also might be possible to 
support 7 receivers if you throw out all support for transmitting.

In particular, version 1.8 only supports 2 receivers. I don't know what 
the limits are or have been for Angelia.
