So where's the real source code for it?

I wish I knew.  The vendor released the array of random numbers as GPL 
to us. :-(

If you won't (or can't) provide source code for the microcode then it
should instead be submitted to linux-firmware with a binary
redistribution licence, and the driver should load it with
request_firmware().

I will attempt to do that.

The .c file contains plenty of other pseudo-random numbers, but those 
cannot really be considered 'firmware'
