Yes, I've finished GOST hash core, that's why I asked for more stuff. I 
have Verilog sources and working testbench. I have also written 
gost_tester_eim.c, it verifies that the core operates correctly in 
Novena, much like hash_tester_eim.c checks operation of SHA cores.

I haven't committed GOST core so far, because to my great embarrassment, 
Basil and me still haven't figured out how to generate and sign PGP key. 
I cannot upload anything without this key. I also cannot work with your 
ticket system without this key. Maybe you can give some insight on how 
to do all this dance, as Rob called it?

Speaking of FPGA issues, let's start from (1). What repository contains 
this simplified I2C system? Is it under test/novena_i2c_simple?
