2707541eab Adding DMA source and changing interface
-DMA added as a master driving out transactions
(this is going to be great!!)

842a6d894a Fixing enable/reset:
-Removing enable from ISERDES, not healthy
-Moving all logic to protocol block. (this is an IO block)
-Removing tow redundant pipeline stages (check this??)

d0b04687ea Bug fix, missing pipeline stage on read response
-Apparantly old FIFO was not pipelined (IE data comes back same cycle).
-Not knowing the Xilinx logic, I made it a regular one cycle pipeline
memory based FIFO

2369e92ffa Bug fix, missing "data hold" stage
Hadn't realized that the data needed to be held
Need to look at this logic again!
For now going back to old logic

f141a0e320 Clock cleanup
-Adding enable signal to clock out. Definitely right decision to keep
separate bit from the divider field.
-Fixed settings for to fit new register field
-XILINX version is still broken!!

00a921b839 Changed register map
-Moved "groups" to E,D,C
-Changed names to EL* (shorter is better, clear enough)
-Moved order to fit logical operation during init
-Moved embox registers to MMR group
DONE!

85db5d9de0 Spell checking comments
First time ever using spell cheker in EMACS. Hard to believe...but it's true!
I am sure this speaks volume for how little I have commented my code over the years!

068d63279b Changing ESYSCLK definition (again.....)
old implementation felt too "cutsy"
this makes for a cleaner usage model (simple shift with param)
also splitting out enable but, not making the CTIMER mistake again
