2015-07-17	Adding task to dump fifo contents.	Joachim Strömbergson

2015-07-17	Adding more test functionality in the fifo testbench. Now we generates ↵	Joachim Strömbergson
	several 512-bit words fed into the fifo.
2015-05-22	(1) Added a cipher block statistics counter. (2) Cleaned up the csprng code ↵	Joachim Strömbergson
	and connected discard for fast restart of trng. (3) Added addresses for allowing API to write a known seed to allow test mode. (3) Fixed a number of minor issues during linting. (4) Fixed the csprng testbench to actually generate data as well as displaying the block stat counter.
2015-04-28	(1) Remove the delayed read for EIM (see core/platform/novena commit ↵	Paul Selkirk
	2f58e8f). (2) Add the code to read the csprng name and version registers.
2015-04-27	Adding name and version fields to the csprng.	Joachim Strömbergson

2015-04-27	Updated the trng version number to sometning that better reflects that it ↵	Joachim Strömbergson
	actually builds and generates values.
2015-04-02	(1) Added a state in the write fifo machine to actually drop request between ↵	Joachim Strömbergson
	csprng data words. (2) Updated the testbench with better test vector generation.

	register. Changed to localparam. Removed redundant code for reg updates.
2015-03-26	Minor cleanup: Changed to localparam for internal parameters. Merged reg ↵	Joachim Strömbergson

2014-11-20	Reworked the csprng output fifo to really take advantage of the fact that ↵	Joachim Strömbergson
	the csprng delivers blocks of 512 bits. Removed trailing whitespaces and linted code.
2014-11-20	Updates after linting.	Joachim Strömbergson

2014-11-20	(1) Reducing timepout for entropy sources. Updated interface for sha-512 to ↵	Joachim Strömbergson
