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.

2015-04-01	Cleanup and fixes of calculations.	Joachim Strömbergson

2015-03-26	Minor cleanup: Morged clocked processes. Changed name of api read data hold ↵	Joachim Strömbergson
	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
	update processes to one. Changed name of api read data hold reg and added better update vector name for it.
2015-03-26	Changed to Verilog 2001 part select for word extraction.	Joachim Strömbergson

2015-03-26	More cleanup. Completed parameterization of fifo. Fixed incorrect size of ↵	Joachim Strömbergson
	control regs.

	bit selection.
2015-03-26	Cleanup: Merged separate clocked processes. Fixed incorrect bit widths. ↵	Joachim Strömbergson
	Changed to localparams. Changed api data read reg to real hold register.
2015-03-25	streamline(?) api_mux, register data for eim output	Paul Selkirk

2014-11-20	Updates of variable names to matched changed instance name and new fifo.	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
	match new interface with work factor ports. We are not using the work factor here at the moment.
2014-10-02	Updating testbenches to match new interfaces and use the api to read and ↵	Joachim Strömbergson
	write data.
2014-10-02	Removing wrappers since they are not used.	Joachim Strömbergson

2014-10-02	Updating trng to debugged version.	Joachim Strömbergson

2014-09-27	Adding debug port for mixer and csprng. In the csprng the debug_update will ↵	Joachim Strömbergson
	trigger fifo extraction and thus force random number generation.
2014-09-26	Updating source to the latest and greatest. In this version the entropy ↵	Joachim Strömbergson
	sources works and all modules have correct intterface.
2014-09-26	Removing old fake entropy source.	Joachim Strömbergson

2014-09-26	Removing old fake module for ring oscillator.	Joachim Strömbergson

2014-09-18	Updates after synthesis of the complete trng.	Joachim Strömbergson

	during synthesis.
2014-09-16	Fixed incorrect bit index.	Joachim Strömbergson

2014-09-16	More debug fixes. We add one extra wait cycle to allow the mixer to detect ↵	Joachim Strömbergson
	that we want more seed.
2014-09-16	Debug fixes found during simulation. Now the trng generates data and ↵	Joachim Strömbergson
	provides an api.
