Done.

FWIW, on the USRP we distinguish the hardware rev and whether or not
we've loaded firmware from the host using the Device ID (DID) field.
We also stash MD5 hashes of the FX2 and FPGA firmware we loaded in the
top of the FX2 RAM.  The host fishes them out to determine if it likes
the code that's been loaded or whether it should load new code (and
the corresponding hashes).
