-In the default mode we now have 7 input clocks to basic elink
-This is too many, need to simplify, not reasonable!
-But with all the knobs on the MMCM, performance will be great...
-WIP on bursting...
-moving to "real" Xilinx PLL instantiation
-one PLL for CCLK one for LCLK
-removing clock dividers, can't work at speed, put inside model
-configuration needs to be done differently
-removing pll_bypass signal, can't work with logic
-clocks should be done with hard macro primitives (no logic)
-Removing enable from ISERDES, not healthy
-Moving all logic to protocol block. (this is an IO block)
-Removing tow redundant pipeline stages (check this??)
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
-added register read/write properly
-removed redundant wrapper layers in maxi/saxi
-changed over to "emesh" interface from packet 103 bit data
-cleaned up maxi
-cleaned up saxi
-removed redundant signals in elink interface (user,lock,..)
-added wrapper to fifo (to carry emesh interface through)
Now comes the fun part of testing
